Common Idioms
[B2] Common Idioms in English: a concise guide to everyday phrases, expressions, and idioms used by native speakers. This module helps you understand and speak more naturally in English.
What idioms are
Idioms are fixed expressions whose meaning is not fully predictable from the individual words. They often sound โliteralโ but actually communicate a figurative idea, feeling, or social signal. Because idioms are conventional, you learn them as whole phrases and choose them based on situation and tone.

Everyday reactions
Many common idioms function as quick reactions in conversation, showing agreement, surprise, doubt, or resignation. The key is matching the idiom to your attitude: some sound calm and practical, others sound dramatic or humorous. Use these when you want to respond naturally without a long explanation.
