🧠 Thinking Idioms
English has plenty of colorful ways to describe what happens inside your head. You might lose your train of thought halfway through a sentence, stay on the fence when you cannot decide, or suddenly realize that a name rings a bell.
These 11 idioms cover decisions, limits, memory, shared understanding, appearances, and creative thinking. They are especially useful in everyday conversations because many of them describe situations we encounter constantly.
