What is this instance of using two words in a sentence called? Where the first had indicates a past event, and the second denotes the act of having something. I can't think of another example right now but I have seen this occurrence of two words next to each other in a sentence and wondered if there was a term for that? "That that would happen is terrible" [I thought of another example] The first "that" being used to reference the occurrence of the second "that".
