Idiomatic language
IELTS Speaking

Idiomatic language is the use of words, phrases, or expressions whose meanings are not directly deducible from the literal meanings of the individual words. This includes idioms, colloquial phrases, and some phrasal verbs commonly used by native speakers. For example, the phrase "break the ice" means to start a conversation in a social setting, not to literally break frozen water.

Importance in IELTS Speaking

  • Idiomatic language is specifically mentioned in the IELTS Speaking band descriptors for higher bands, especially Band 7 and above. Examiners look for the natural and flexible use of idiomatic expressions as a sign of a candidate's fluency and ability to communicate like a native speaker.
  • Using idiomatic language appropriately can demonstrate a wider range of vocabulary and the ability to speak more naturally. However, incorrect or forced use can negatively impact clarity and coherence.
  • For example, a candidate might say, "I was over the moon when I passed my exam," to express great happiness. This shows knowledge of idiomatic language and helps convey meaning more vividly.

Key Points

  • Idiomatic language should be used appropriately and naturally, not overused or forced into answers.
  • It is not necessary to use idioms in every response, but occasional, accurate use can enhance your score for lexical resource.
  • Clear communication is more important than using complex expressions, so candidates should only use idioms they understand well.
