To explain from another direction, and add to the replies you're getting that explain it directly, C++ is a language that does its best to not break existing codebases. When they want to introduce a new concept (in this case, a way to express that using an implicit function or overload is forbidden) they use one of the already-reserved keywords ("delete"). This sometimes leads to a clunky reading experience, but is better than breaking anyone's code that happens to use a variable or function named "forbidden" or similar.
