These are two definitions from the Farlex Dictionary of Idioms (2022 edition) What's the difference between these two definitions? It seems to me like both of these definitions mean exactly the same except for the usage note which says that you can insert a noun or pronoun between "hold" & "out" using one of them. What gives?
verb To keep something from someone or something else, especially information or money. Someone still needs to chip in three more bucks to cover the bill. Who's holding out? Are you holding out on me? Do you know more details about the merger than you're letting on?
verb To withhold someone or something (from something). In this usage, a noun or pronoun can be used between "hold" and "out." I heard that Sarah's parents are holding her out of play rehearsals because she has the mumps. Hold these pink cupcakes out for now—there's more than enough already on the table.
