Teaching Idiomatic Expressions: A Practical Guide for Pre-Service Teachers of English

Why Teach Idioms?

Idioms are fixed expressions whose meanings cannot usually be understood from the meanings of the individual words.

For example:

• Break the ice ❌ (not literally breaking ice)
• Meaning: To start a conversation and reduce tension.

Students who know grammar and vocabulary may still struggle to understand native speakers because everyday English contains thousands of idioms.

As future English teachers, pre-service teachers should learn how to teach idioms through communication rather than memorization.

1. Story-Based Learning

What is it?

Instead of presenting idioms as a list, introduce them through a meaningful story. Context helps learners infer meaning naturally.

Why it works

Our brains remember stories much better than isolated facts. Stories provide emotional and situational cues that make idioms easier to recall.

Classroom Example

Target Idioms

• Break the ice
• Spill the beans
• Hit the nail on the head

Story

On the first day of college, everyone was nervous. The teacher told a funny joke to break the ice. Later, Priya accidentally spilled the beans about the surprise farewell party. During the discussion, Rahul hit the nail on the head by identifying the real problem.

Teacher Activity

Ask students:

• What happened first?
• Which phrase means "to reveal a secret"?
• Which phrase means "to say exactly the right thing"?

Students infer meanings before the teacher confirms them.

2. Picture Guessing Technique

What is it?

Use pictures to stimulate curiosity and encourage learners to predict the idiom.

Example

Display:

🐱 + 🎒

Students guess:

"Cat in the bag?"

Teacher reveals:

Let the cat out of the bag

Meaning:

Reveal a secret accidentally.

Follow-up

Students create their own sentence.

My brother let the cat out of the bag by telling my parents about the surprise trip.

3. AI Image Generation

What is it?

Use AI tools to create humorous literal illustrations of idioms, then contrast the literal and figurative meanings.

Example

Generate an image of:

A businessman literally "hitting a nail on the head" with a hammer during a meeting.

Ask:

• What is happening?
• Is this literal or figurative?
• What does the idiom actually mean?

Students enjoy the humor while remembering the figurative meaning.

Teaching Tip

Ask learners to create their own AI-generated idiom illustrations and explain them to classmates.

4. Comic Strip Method

What is it?

Present an idiom through a sequence of events rather than a definition.

Example

Comic:

Frame 1

Everyone is silent.

Frame 2

Teacher tells a funny joke.

Frame 3

Everyone laughs.

Caption:

Break the ice

Students identify:

• situation
• emotion
• meaning

5. Role Play and Drama

What is it?

Students perform situations where idioms naturally occur.

Example

Situation:

Two friends preparing for exams.

Required idioms:

• Burn the midnight oil
• Piece of cake
• Pull yourself together

Dialogue:

A:
"I had to burn the midnight oil yesterday."

B:
"Don't worry. This exam will be a piece of cake."

6. Movie and TV Clip Analysis

What is it?

Use authentic media where idioms occur naturally.

Procedure

Students watch a short clip.

Identify:

• idiom
• speaker
• context
• emotion
• intended meaning

Reflection

Why did the speaker choose an idiom instead of literal language?

7. Song-Based Learning

Songs often repeat idioms, making them memorable.

Example

Idiom:

Every cloud has a silver lining

Discuss:

• What is a cloud?
• What is silver?
• What does the expression really mean?

Students relate it to their own lives.

8. Corpus-Based Discovery Learning

What is it?

Instead of giving definitions, learners investigate authentic language data using corpus tools.

Example

Search:

Break the ice

Students discover examples like:

• The trainer told a joke to break the ice.
• Games helped break the ice.

Questions:

• Who usually breaks the ice?
• In what situations?

Students discover usage patterns themselves.

9. Idiom Maps

Organize idioms by themes.

Example

Happiness

• On cloud nine
• Over the moon
• Walking on air

Anger

• Blow one's top
• Hit the roof
• See red

Success

• Hit the jackpot
• Go places
• Come out on top

Students create mind maps connecting similar idioms.

10. Idiom Diary

Each learner maintains an idiom journal.

Idiom	Meaning	Example	Where I Heard It
Under the weather	Slightly ill	I stayed home because I was under the weather.	Podcast

This encourages continuous learning.

11. Social Media Collection

Students search YouTube, podcasts, interviews, or social media for naturally occurring idioms.

Assignment

Collect:

• five idioms
• context
• speaker
• intended meaning

Present findings in class.

12. Idiom of the Week

Instead of overwhelming students, teach one carefully selected idiom each week.

Example

Week 1

Hit the books

Activities:

• meaning
• dialogue
• role play
• writing task
• classroom poster

Repeated exposure improves retention.

13. AI Conversation Partner

Students interact with AI.

Sample Prompts

"Explain the idiom 'once in a blue moon.'"

"Create five dialogues using this idiom."

"Correct my use of this idiom."

"Quiz me tomorrow."

AI provides unlimited personalized practice.

14. Gamification

Learning through games increases motivation.

Examples include:

• Idiom Bingo
• Charades
• Pictionary
• Escape Room
• Crossword puzzles
• Matching cards
• Kahoot quizzes

Example

Teacher acts:

Butterflies in my stomach

Students guess the idiom.

15. Body Language Integration

Many idioms are linked with gestures.

Examples

Idiom	Gesture
Fingers crossed	Cross fingers
Face the music	Confident posture
Turn your back	Physically turn away
Keep your chin up	Raise head

Students perform gestures while saying idioms.

This combines verbal and nonverbal learning.

16. Idiom Timeline

Teach the historical origins of idioms.

Example

Bite the bullet

Origin:

Before anesthesia, soldiers bit bullets during painful surgery.

Modern meaning:

Face something difficult bravely.

Students remember stories better than definitions.

17. Cross-Cultural Comparison

Ask students:

"What expression in your mother tongue has a similar meaning?"

Example:

English:

"Don't count your chickens before they hatch."

Students compare equivalent expressions from Gujarati, Hindi, Tamil, Bengali, or other languages.

This builds intercultural awareness.

18. Situation Matching

Provide real-life situations.

Example:

Situation:

"I accidentally revealed our surprise party."

Students choose:

✅ Spill the beans

rather than memorizing definitions.

19. Idiom Flashcards

Front:

Burn the midnight oil

Back:

• Meaning
• Example
• Picture
• Synonym
• Opposite
• Memory tip

Students review regularly using spaced repetition.

20. Concept-Based Teaching

Teach idioms through underlying concepts.

Theme	Idioms
Journey	At a crossroads, On the right track, Go the extra mile
Food	Piece of cake, Spill the beans, Bigger fish to fry
Weather	Under the weather, Storm in a teacup, Save for a rainy day
Sports	Get the ball rolling, Move the goalposts, Level playing field
Animals	Let the cat out of the bag, Dark horse, Copycat

Students recognize recurring metaphors in English.

21. Personalization

Ask learners to connect idioms with their own experiences.

Example:

Describe a time when you had to bite the bullet.

Personal connections make learning meaningful and memorable.

22. Creative Idiom Creation

Encourage learners to invent modern idioms.

Example

Running on 1% battery

Meaning:

Trying to continue despite extreme tiredness.

Students explain:

• literal meaning
• figurative meaning
• context
• dialogue

This develops creativity and metaphorical thinking.

Key Takeaways for Pre-Service Teachers

• Teach idioms in context, not as isolated lists.
• Encourage learners to discover meanings before providing explanations.
• Combine visuals, stories, gestures, and authentic media to create memorable learning experiences.
• Use AI and digital tools to generate examples, images, dialogues, and personalized practice.
• Reinforce learning through retrieval practice and repeated use in speaking and writing.
• Connect idioms to learners' experiences and cultures, making them meaningful and transferable.

By using these approaches, pre-service teachers move beyond teaching what an idiom means to helping learners understand when, why, and how to use idiomatic language naturally in real communication.
