1. time, possibility, or space for something
there is room for improvement/no room for error
The noun 'room' is sometimes used as a substitute for the word 'space' in English when talking about where something fits within a physical place. If you say there is 'room for' something, it means there is space for it or that something can fit. You can use this to talk about physical objects, 'there is no room for a desk over there' or you might say there is 'room for improvement' meaning there is a gap between your current level and where you are expected to be.
