Frequently Asked Questions
What is an idiom in English?
An idiom is a phrase or expression whose meaning cannot be understood from the literal meanings of its individual words. For example, 'break a leg' does not mean to injure yourself — it means 'good luck'. English has thousands of idioms that are essential for natural, fluent communication.
Why are idioms important to learn?
Idioms are everywhere in everyday English — in films, news, conversations, and books. Understanding them helps you comprehend native speakers and sound more natural yourself. They are also frequently tested in IELTS, TOEFL, and Cambridge English examinations.
What CEFR level do I need to understand idioms?
Most common idioms are introduced at B1 (intermediate) level. More complex idioms appear at B2 and C1. Learners at A1 and A2 are not usually expected to know idioms, but may encounter very common ones in context.
How many English idioms are there?
English has over 25,000 idioms according to some estimates. However, a working vocabulary of 200–500 of the most common idioms will cover the vast majority of everyday communication situations.
What is the difference between an idiom and a phrasal verb?
A phrasal verb is a verb combined with a preposition or adverb that creates a new meaning (e.g. 'give up', 'look after'). An idiom is a longer, fixed phrase whose meaning is completely figurative (e.g. 'break a leg', 'once in a blue moon'). Some phrasal verbs are also idiomatic. You may also want to explore English collocations — fixed word combinations that sit between single vocabulary items and full idioms.
Can I use idioms in formal writing?
Generally, no. Idioms are typically informal and are best suited to spoken English, casual writing, and creative texts. In formal reports, academic essays, or official letters, plain, precise language is preferred over idiomatic expressions.
How do I learn idioms effectively?
The best approach is to learn idioms in context: read example sentences, listen for them in podcasts and films, and practise using them in your own sentences. Tools like LexFizz's Flip Tiles and Flash Cards exercises help you memorise idioms through active recall. For idioms used in professional settings, see our guide to business English phrases. You can also quiz yourself on vocabulary to reinforce what you have learned.
Do idioms change over time?
Yes. Some older idioms fall out of use, and new ones emerge constantly — especially from sport, technology, and popular culture. The idioms on LexFizz are current and widely used in contemporary English.
Are English idioms the same in American and British English?
Many idioms are shared across varieties, but some differ. For example, British English uses 'touch wood' while American English uses 'knock on wood'. Both mean the same thing — hoping for good luck. Context usually makes the meaning clear regardless of dialect.
Where can I practise English idioms?
LexFizz offers Flip Tiles and Flash Cards exercises that are great for practising idioms. You can also explore the Grammar Glossary for definitions of language terms, and the blog for articles on common English expressions.
