What term means "all of the words one knows"?
What term, ideally used by linguists, refers to the entire collection of words that a person knows? For example, if someone opened up a dictionary, and created a list of all of the words they know, what term would refer to that list?
Solution 1:
You mean one's (personal) vocabulary?
Merriam-Webster says:

Solution 2:
