Idiomatic Range for Speaking: Natural Idioms and Phrasal Verbs That Don't Sound Forced

The IELTS Speaking marking criteria explicitly state that achieving Band 7.0 or higher in Lexical Resource requires the flexible and accurate use of idiomatic language. However, dropping outdated, obscure idioms—such as it's raining cats and dogs or kick the bucket—into modern context sounds forced and unnatural. High-scoring candidates use natural phrasal verbs, idiomatic collocations, and everyday spoken expressions seamlessly.

Essential Phrasal Verbs for High-Scoring Speech

Burn out: To become exhausted from overwork.

Example: "If university students don't balance their studies with leisure, they inevitably burn out."

Pick up (a skill): To acquire a language or ability naturally through practice.

Example: "Living abroad allowed me to pick up conversational French much faster than studying in a classroom."

Wind down: To relax after a period of stress or hard work.

Example: "Listening to classical music is my go-to method for winding down in the evening."

Natural Idiomatic Expressions

Once in a blue moon: Rarely or infrequently.

Example: "Given my busy schedule, I only get to play golf once in a blue moon."

Over the moon: Extremely pleased or thrilled.

Example: "I was absolute over the moon when I received my exam results."

Cost an arm and a leg: Very expensive.

Example: "Renting an apartment in central London costs an arm and a leg these days."

Ensure every idiom fits the context naturally; authentic usage always trumps forced complexity.
