How to Improve Diction in English

If you're currently learning English, you know that speaking clearly is just as important as knowing the right words. 

In this guide, you'll learn what diction is, the different types of diction there are, how to spot it in literature, and how to improve it step by step. We'll also show you how the Promova platform can help you practice and master diction in your everyday English learning routine.

Let's begin!

What is diction?

Diction refers to the way a person chooses to use words when speaking or writing, including how those words are pronounced. Your diction plays a big role in how your message comes across to others.

When your diction is clear and appropriate, people can easily understand what you're trying to say. But if your diction is confusing or unclear, your message might be misunderstood — or even ignored.

There are two main parts of diction:

  • Word choice: Do you use simple or complex words? Formal or informal ones?
  • Pronunciation and clarity: Do your words sound clear and easy to understand when you speak?

For example, you might use casual diction when talking to or texting a friend, but it's best to use formal diction for occasions like a job interview. In short, diction can be serious, poetic, technical, funny, or friendly — it all depends on who you're talking to and what you want to say.

The different types of diction in English

There are many diction types you'll hear and use in everyday life. Let's take a closer look at the most common of them:

Type of dictionDescriptionExample sentence
Formal diction
  • Formal diction is the most proper and polite style of speaking or writing. It follows all grammar rules and often uses more advanced or sophisticated vocabulary. 
  • You'll find formal diction in academic papers, professional emails, business meetings, or official speeches. It avoids casual words, slang, or contractions like "can't" or "won't."
"I am delighted to make your acquaintance." (This is a polite way to say "Nice to meet you.")
Informal diction
  • Informal diction sounds more relaxed and friendly. It's perfect for chatting with friends, texting, or writing a personal email. 
  • This type of diction often includes everyday language, contractions ("it's," "you're," etc.), and simple sentence structure.
"It's nice to meet you!" (This version is shorter, more natural, and great for casual conversations.)
Colloquial diction
  • Colloquial diction includes expressions or phrases that are commonly used in certain areas or cultures. It sounds very natural and shows how real people talk in their daily lives.
  • This type of speech often changes from region to region and may not always be understood by everyone.
"Wanna hang out later?" (Common in spoken American English.)
Slang diction
  • Slang is a very informal type of diction, often used by younger people or within certain social groups. 
  • Fun and expressive slang words tend to come and go quickly. 
"That movie was lit!" (Meaning the movie was very fun, cool, or exciting.)
Technical diction
  • Technical diction uses special vocabulary related to a specific field or profession. For example, doctors, lawyers, and scientists use specialized technical terms when communicating with colleagues in their respective fields.
  • Technical diction helps specialists communicate clearly with each other.
"The patient's symptoms suggest acute bronchitis." (This sentence uses medical terms for a specific diagnosis.)
Poetic diction
  • Writers and poets use poetic diction to create images, feelings, and sounds in the reader's mind. 
  • It often includes metaphors, similes, alliteration, and other artistic language. Its diction is more emotional and imaginative than regular conversation.
"The stars danced in the velvet sky." (This sentence uses poetic language to create a dreamy image of the night sky.)
Abstract diction
  • Abstract diction includes words that talk about ideas, emotions, or qualities — things you can't touch, see, or hear. 
  • These words are often more general and require deeper thought or explanation.
"Her kindness was boundless." (You can't physically see "kindness," but the sentence gives you a strong emotional picture.)
Concrete diction
  • Concrete diction uses words that describe specific, physical things — something you can experience with your senses. 
  • These words help your reader or listener create a clear image.
"The red apple was crisp and juicy." (This sentence makes you imagine the color, sound, and taste of the apple.)

Mastering all types of diction can really help you sound more confident in English. It also makes your speech clearer and easier to understand.

How to Improve Diction in English

Examples of diction in English

To better understand diction, let's look at some famous diction examples we can find in classic and modern literature:

Formal diction:

  • "It was the best of times, it was the worst of times…" — Charles Dickens, A Tale of Two Cities

Dickens' opening is a classic example of elevated and structured language, setting a serious and dramatic tone for the rest of the novel.

Informal diction:

  • "You is kind. You is smart. You is important."— Kathryn Stockett, The Help

Stockett's use of non-standard grammar effectively conveys a character's dialect and creates a warm, intimate feeling.

Colloquial diction:

  • "It's no use going back to yesterday because I was a different person then." — Lewis Carroll, Alice's Adventures in Wonderland

Carroll's phrasing captures a childlike and whimsical tone.

Slang diction:

  • "You're being super salty right now." — Jenny Han, To All the Boys I've Loved Before

Han's use of the word "salty" (upset, bitter, or annoyed) is a perfect example of contemporary slang used to connect with a younger audience.

Technical diction

  • "This case is as simple as black and white. The defendant is not guilty, but somebody in this courtroom is." — Harper Lee, To Kill a Mockingbird

Lee's dialogue incorporates specific legal terms, fitting the courtroom setting and adding realism.

Poetic diction:

  • "Shall I compare thee to a summer's day?" — William Shakespeare, Sonnet 18

Shakespeare's language in this sonnet is intentionally beautiful, rhythmic, and often uses archaic or elevated vocabulary.

Abstract diction:

  • "There is no greater agony than bearing an untold story inside you." — Maya Angelou, I Know Why the Caged Bird Sings

Angelou's quote uses words that represent ideas ("story") and feelings ("agony") rather than tangible objects.

Concrete diction:

Describes the texture ("sticky"), color ("green"), taste ("chocolate"), of a cake and what's written on it, which makes it easier to imagine for the readers.

By noticing the different kinds of diction in books, movies, or podcasts, you can become more aware of how language sets the tone of each message.

Tips and exercises to improve your diction 

Improving your English diction means working on two key aspects: your word choice and your pronunciation. These skills help you speak and write more clearly, sound more natural, and express your thoughts with confidence.

Here are some beginner-friendly tips and simple exercises to help you get some diction practice:

1. Expand your vocabulary in English

Growing your English vocabulary is essential for better communication, whether you're writing, speaking, reading, or listening. It's a key part of becoming fluent and feeling comfortable in any English-speaking environment, whether formal or informal.

Exercise: Learn 5 new English words a day. Then write one short sentence using each word.

2. Read aloud

Reading out loud is a great way to practice pronunciation and fluency, as this helps you train your tongue and voice to say words clearly.

Exercise: Choose stories, dialogues, or short articles you enjoy and read for at least 5–10 minutes each day, focusing on clarity and tone.

3. Record yourself

Recording your voice might feel strange at first, but it's very helpful. When you listen to yourself, you can notice what you're doing well and what needs improvement, especially with pronunciation, speed, or tone.

Exercise: Record yourself reading a paragraph. Then listen and note words that are unclear. Practice them again until you can pronounce them confidently.

4. Practice with tongue twisters for diction

Tongue twisters are fun phrases that are tricky to say quickly. They help your mouth get used to moving faster and more accurately.

Exercise: Try saying, "She sells seashells by the seashore" five times fast!

5. Mimic native speakers

One of the best ways to improve your diction is by copying how native English speakers talk. Listen carefully to their pronunciation, intonation, and emotion. You'll pick up natural rhythm, phrasing, and common expressions.

Exercise: Choose a short video clip (maybe from a TV show or a YouTube video). Listen to one sentence at a time, then pause and repeat it out loud exactly as they said it. Try to match the tone, stress, and feeling.

6. Focus on word stress and rhythm

English has stress-timed rhythm, which means that some words in a sentence are said more strongly than others. It can actually change the meaning of a sentence, even if the words stay the same!

Exercise: Practice saying, "I didn't say she stole my money" and repeat it 7 times, each time stressing a different word. It will help you understand how English rhythm works and how powerful word stress can be!

These exercises will help you gradually strengthen your English-speaking skills and feel more confident when communicating. Keep practicing and you'll see great results!
