The quiz draws 10 random idioms and pairs each with three wrong meanings pulled from the same set, so you cannot guess by tone alone.
59 curated English idioms, each spread across 45 topical categories and tagged beginner, intermediate or advanced. Every entry carries a meaning, a literal reading, a usage note, an origin, two example sentences, synonyms and related idioms.
It picks 10 idioms at random and shows each with four possible meanings, one correct and three taken from other idioms in the collection. Your running score is shown as you go, and at the end you get the total out of 10 plus a percentage.
An idiom's meaning cannot be worked out from the words themselves, which is why each entry lists the literal reading separately. "Break the ice" literally means breaking frozen water, but it is used for easing tension when a conversation starts, and seeing both side by side is what makes the gap obvious.
