الأسئلة الشائعة

Can I use these idiomatic expressions in formal writing?
Most of them — like 'a grey area', 'a double-edged sword', and 'come to a head' — are perfectly acceptable in formal essays and reports. 'Be on the same page' is more conversational, so use it in emails and meetings rather than academic papers.
How do I remember idiomatic expressions without mixing them up?
Link each expression to a vivid personal situation. For example, think of a real decision that had good and bad sides when you study 'double-edged sword'. Emotional memory is far stronger than rote memorisation.
Is 'cut corners' always negative?
Yes — 'cut corners' always implies that something important was sacrificed for speed or cost. It carries a negative meaning, so don't use it to describe efficient work.
What is the difference between an idiom and a fixed phrase?
An idiom's meaning can't be guessed from its individual words (e.g. 'cut corners' has nothing to do with actual corners). A fixed phrase is a set expression whose words stay the same, and its meaning may be more literal. Both are important at C1 level.
