Frequently asked questions
What is an idiom?
An idiom is a phrase whose meaning is different from the meanings of its words. “It’s raining cats and dogs” has nothing to do with pets; it means it is raining hard.
Why are idioms hard to learn?
You can’t work them out word by word, and many come from old customs or stories. Reading widely, and noticing idioms in context, is the best way to learn them.
Where do idioms like “Achilles’ heel” come from?
Some come from myths and history. In Greek legend, the hero Achilles could only be wounded in his heel, so an Achilles’ heel is a weak spot.
