Idioms and Phrases in the 21st Century

Three learners review open books together at a classroom table, with stacks of textbooks, stationery and a whiteboard in the bright room.

This Punggol page keeps the same 2014 title—but it now has a very practical job.

The original article listed ten expressions and encouraged students to make their writing sound contemporary.

We are keeping those ten expressions.

Instead of treating them as a vocabulary list, we are turning them into a phrase laboratory.

Can a Punggol student recognise what kind of phrase this is, understand its register, use it naturally, switch it into formal English when needed, and reject it when it does not fit?

That is the learning job here.

For the broader theory of living language, register and how expressions change over time, see eduKateSingapore — Idioms and Phrases in the 21st Century.

For composition editing—when phrases help, collide or should be deleted—see eduKateSG — Idioms and Phrases in Composition.

The Punggol phrase lab has four moves

  1. Decode: what does the expression mean?
  2. Place: who would naturally say it and in what situation?
  3. Switch: how would the same meaning sound in formal, neutral and informal English?
  4. Transfer: can the student use it in a new context without copying the model sentence?

This is more valuable than memorising a definition because it trains control.

Why register matters in Singapore

A student may use different English with:

  • a close friend;
  • a teacher;
  • a school principal;
  • a grandparent;
  • a class group chat;
  • a formal email;
  • a composition narrator;
  • a fictional character.

The language system changes because purpose, audience and context change.

MOE’s English Language Syllabus 2020 explicitly frames language use around purpose, audience, context and culture. MOE — English Language Syllabus 2020.

Good English is not one voice used everywhere. It is the ability to move between appropriate voices without losing meaning.

Phrase 1: “take things easy” / “take it easy”

Meaning: relax, avoid unnecessary stress or effort, or approach something calmly.

Register: informal to neutral.

Natural Punggol context:

“Your paper is tomorrow. You’ve already revised. Take it easy tonight and sleep properly.”

Formal switch:

He was advised to reduce his workload and rest before the examination.

Misuse to avoid: using it where the situation requires urgency or precise safety instructions.

Phrase 2: “suck it up”

Meaning: accept an unpleasant situation and continue without complaining.

Register: very informal and potentially harsh.

The phrase can sound unsympathetic because it dismisses the other person’s discomfort.

Dialogue where it might fit:

“It’s raining and we’re already late. We’ll have to suck it up and walk to the bus stop.”

Better neutral switch:

We will have to accept the inconvenience and continue.

Do not use: when someone is describing serious pain, fear, grief or a problem that deserves care.

Register is not only formality. It also carries attitude.

Phrase 3: “keep in touch”

Meaning: continue communicating after people separate.

Register: neutral and widely usable.

Natural context:

“Even after we go to different secondary schools, let’s keep in touch.”

Formal switch:

I hope we can remain in contact after the programme ends.

This is a good example of a simple fixed phrase that sounds natural without trying to look advanced.

Phrase 4: “speak of the devil”

Meaning: said when a person being discussed unexpectedly appears.

Register: informal conversational idiom.

Scene:

“We were just wondering whether Amir would come—speak of the devil, there he is.”

The phrase is playful. It does not literally mean the person is evil.

Formal switch:

Coincidentally, Amir arrived just as we were discussing him.

Phrase 5: “slip past”

This one reveals a useful problem in the old 2014 list.

Not every multi-word expression is an idiom.

Slip past can be fairly literal: move quietly or narrowly beyond someone or something.

The cat slipped past the half-open gate before anyone noticed.

In another context it can become more figurative:

One spelling mistake slipped past the final check.

The student should learn phrase behaviour, not force every phrase into the label “idiom”.

Phrase 6: “send me up the wall” / “drive me up the wall”

Meaning: annoy someone greatly.

Register: informal.

In contemporary English, drive me up the wall is generally the more familiar form.

“That repeating alarm is driving me up the wall.”

Formal switch:

The repeated alarm was extremely irritating.

Notice that the formal version is less vivid but more direct.

Phrase 7: “you got me”

This phrase is context-sensitive.

It can mean:

  • “I don’t know the answer.”
  • “You caught me.”
  • “You understood or convinced me.”

Example 1:

“Why does the LRT stop longer here?” “You got me.”

Meaning: I do not know.

Example 2:

“You said you didn’t eat the biscuit, but the crumbs are on your shirt.” “Okay, you got me.”

Meaning: you caught me.

This is why students need examples, not only definitions.

Phrase 8: “hit it off”

Meaning: quickly become friendly or comfortable with someone.

Register: informal to neutral.

The two new classmates hit it off during orientation and spent the rest of the day together.

Formal switch:

The two students developed an easy rapport almost immediately.

Both sentences are good English.

They belong to different registers.

Phrase 9: “mixed up in”

Meaning: involved in a situation, often a troublesome one.

Register: informal to neutral.

She did not want to get mixed up in an argument that had nothing to do with her.

Formal switch:

She did not want to become involved in an unrelated dispute.

Again, the phrase has a social flavour the formal verb lacks.

Phrase 10: “in summary”

This is not an idiom.

It is a discourse marker used to signal that a writer is condensing previous points.

Register: formal/neutral written English.

In summary, the experiment supports the hypothesis but does not prove that the relationship applies under all conditions.

This is exactly why the 2014 list is useful today.

Ten “phrases” turn out to contain several different language tools.

The original 10, classified

ExpressionUseful classificationRegister

Why classification helps writing

If a student thinks everything is an idiom, every expression is used for the same purpose: “make writing better”.

Once classified, the tools separate.

  • An idiom can compress a figurative meaning.
  • A collocation makes word choice sound natural.
  • A phrasal verb keeps everyday English fluent.
  • A discourse marker organises reasoning.
  • A slang expression signals group identity and informality.

Tool awareness creates control.

Register switch 1: friend → teacher

Friend:

“I got mixed up in something after CCA and missed the bus.”

Teacher:

“I became involved in an issue after CCA and missed my bus. I apologise for being late.”

Same event.

Different receiver.

Register switch 2: group chat → formal email

Group chat:

“You got me. I have no idea what time the meeting starts.”

Formal email:

“I am unsure of the meeting time. Could you please confirm it?”

The informal phrase disappears because the formal task needs clarity.

Register switch 3: composition dialogue → narration

Dialogue:

“That drilling is driving me up the wall!” Hana shouted.

Narration:

The repeated drilling had irritated Hana all morning.

The narrator does not have to sound identical to the character.

Punggol practice route: the LRT platform

Imagine two students waiting for a train.

Write three versions of the same interaction:

  1. two close friends talking;
  2. a student asking a station staff member;
  3. a narrator describing the scene in a composition.

The vocabulary should change even though the physical location remains identical.

Punggol practice route: sudden rain

A thunderstorm begins while students are walking home.

Use these language jobs:

  • one natural conversational phrase;
  • one precise weather description;
  • one formal sentence explaining why they changed route;
  • one sentence with no idiom at all.

This teaches variation rather than phrase density.

Punggol practice route: group project

A group of four students prepares a presentation.

One member keeps changing the slides at the last minute.

Possible informal dialogue:

“You’re driving me up the wall. Can we stop changing everything?”

Formal reflection:

Repeated last-minute revisions made coordination difficult.

Same meaning field.

Different representation.

The phrase should match the age of the character

The old 2014 article correctly noticed this.

A child character should not sound like an elderly academic unless the story gives a reason.

An adult professional should not suddenly use youth slang only because the student writer recently learned it.

Ask:

  • How old is the speaker?
  • Who are they speaking to?
  • What relationship exists?
  • What year is the story set in?
  • What social group does the phrase signal?

The phrase should match the emotional state

People speak differently when:

  • angry;
  • embarrassed;
  • afraid;
  • trying to be polite;
  • speaking to authority;
  • joking with friends.

A memorised phrase that ignores emotion can make dialogue sound theatrical.

The phrase should match the purpose

Why is the speaker talking?

  • to persuade;
  • to apologise;
  • to joke;
  • to warn;
  • to explain;
  • to request;
  • to comfort.

The same person can use different registers because the purpose changes.

The 3-column notebook

For each new phrase, make three columns:

ExpressionNatural contextFormal switch
hit it offnew classmates become friendsdevelop rapport quickly
keep in touchfriends after graduationremain in contact
mixed up inunwanted involvementbecome involved in
drive me up the wallstrong informal irritationcause significant irritation

This builds a switching system rather than one fixed sentence.

The 5-sentence transfer drill

Choose one phrase and write it in five different situations.

  1. home;
  2. school;
  3. CCA;
  4. public transport;
  5. fictional story.

If the phrase sounds natural only in one context, that is useful information.

Do not force it into all five.

The reject drill

Students need practice saying:

This phrase is correct English, but wrong here.

Give three sentences and ask which should not use the expression.

This is harder than simple recall and much closer to real writing.

The plain-English drill

Translate every idiom back into direct English.

If a student cannot explain the phrase without using the phrase, understanding may still be shallow.

The dialogue-aloud drill

Read the sentence aloud as though speaking to a real person.

Many unnatural phrases reveal themselves immediately when spoken.

Writing has an ear as well as an eye.

The message-to-email switch

Take one informal text message and rewrite it as a formal email.

Example text:

“Hey, you got me—I don’t know when the thing starts. Can you check?”

Formal email:

“I am unsure of the programme’s starting time. Could you please confirm the schedule?”

This is useful preparation for functional writing because meaning remains while register changes.

The composition-to-report switch

Narrative:

“Speak of the devil,” Mei whispered as Aaron stepped into the classroom.

Report:

Aaron entered the classroom shortly after the group had discussed his absence.

Students learn that register switching is not “making vocabulary harder”.

It is selecting the right representation.

Primary 3–4 practice

  • Understand the plain meaning.
  • Match phrase to a picture or simple scene.
  • Choose between formal and informal examples.
  • Say one natural sentence aloud.

At this level, control matters more than quantity.

Primary 5–6 practice

  • Classify phrase type.
  • Use in dialogue.
  • Rewrite into formal English.
  • Identify a misuse.
  • Retrieve a week later.

This connects vocabulary to PSLE composition, comprehension and situational writing.

Secondary practice

  • Analyse register and connotation.
  • Compare idiom with direct analytical wording.
  • Identify cultural or generational signals.
  • Rewrite across genres.
  • Discuss whether the phrase is cliché, current, local or specialised.

The same phrase bank becomes a more sophisticated object as the learner develops.

Do not upgrade every simple phrase

Students sometimes believe:

simple = weak.

That is false.

“Keep in touch” is simple and natural.

Replacing it with “maintain communicative correspondence” would usually make ordinary dialogue worse.

Advanced English is not the longest available version of the sentence.

Do not make every young character speak internet slang either

Contemporary does not mean maximum trend language.

Most real speech mixes ordinary durable expressions with a smaller amount of group-specific language.

A composition overloaded with current slang can feel less believable because it sounds like the writer is trying to prove the story is modern.

Phrases age at different speeds

Some idioms remain understandable for generations.

Some slang belongs to a short moment.

Some expressions survive but change tone.

This is why the old 2014 list is valuable.

We can revisit it and ask:

  • Does this still sound natural?
  • Has the dominant form changed?
  • Is it still informal?
  • Would a child use it now?
  • Has its meaning shifted?

Language change should be observed, not guessed

Use dictionaries, reading, listening and real conversation.

A teacher’s memory of what sounded modern twenty years ago is not enough.

A student’s group chat is not the whole English language either.

Good judgement samples multiple contexts.

A weekly Punggol phrase routine

  • Monday: learn two expressions in context.
  • Tuesday: paraphrase them in plain English.
  • Wednesday: write informal and formal versions.
  • Thursday: use one in composition dialogue.
  • Friday: identify one sentence where it does not belong.
  • Next week: retrieve without notes.

Two phrases controlled well are more useful than twenty phrases recognised vaguely.

The phrase confidence ladder

  1. I have seen it.
  2. I know roughly what it means.
  3. I can explain it plainly.
  4. I know whether it is formal or informal.
  5. I can recognise a natural context.
  6. I can use it in a new sentence.
  7. I can switch it into another register.
  8. I can reject it when it does not fit.

Level 8 is stronger than a memorised list.

What progress looks like

  • Students stop calling every phrase an idiom.
  • Dialogue sounds age-appropriate.
  • Formal emails become less conversational.
  • Composition uses fewer forced expressions.
  • Students can paraphrase figurative language.
  • Phrasal verbs and collocations become more natural.
  • Students notice when a phrase is too harsh, too casual or too vague.
  • Students retrieve phrases after delay rather than only copying model sentences.

Frequently asked questions

Are all ten original expressions idioms?

No. The list contains idioms, fixed phrases, conversational expressions, verb phrases and a discourse marker. That distinction is now part of the lesson.

Is “suck it up” suitable for school composition?

It can fit informal dialogue for a suitable character, but it is harsh and highly informal. It should not be inserted into formal writing or sensitive situations merely because it appears on a vocabulary list.

Is “in summary” an idiom?

No. It is a discourse marker that signals summarising and is more useful in formal explanatory or argumentative writing than in ordinary dialogue.

How many phrases should a student learn each week?

There is no fixed number. A small set learned with meaning, register, retrieval and transfer can be more valuable than a large list memorised shallowly.

Why does Punggol need a separate idioms page when eduKateSingapore has one?

This page owns practice. The eduKateSingapore sibling explains language change and register at a broader level; eduKateSG owns composition editing. This Punggol page is the student-facing phrase lab.

The original 2014 idea, properly taught

The old article said:

keep your language contemporary.

We would say it more precisely now.

Know what the phrase means. Know who would say it. Know who is receiving it. Know what register it belongs to. Then choose it—or deliberately leave it out.

That is how a vocabulary item becomes usable English.
