There is the tag for word-ladder, the connecting of two words e.g LEAD into GOLD. However, it is rarely used: 6 questions are tagged as such, although there have been many puzzles that are actually word ladders but don't have the tag, such as the one I linked.
They are usually tagged with wordplay, letters or something similar but not as the actual word ladder puzzle that it is.
Should questions be retagged or something? Or does it not matter all that much?
