Thus, the DM is about to make a pun about Fall damage. The player of the bard notices the incoming pun, takes defensive action via casting a counter-pun spell, and thus prevents a table full of groaning and moaning, and possibly even laughter.
Because no one else is doing it, I'm going to take the hit. Feather Fall in D&D 5e prevents falling damage, not fall damage. Sorry to ruin the pun, but someone had to.
The English language still backs it up. If you fall, you are falling. Simply because there is an ing missing from the text of a thing not said in the joke doesn't mean that the joke doesn't work. On top of that there's the whole part of how the DM is God in a game, not the DMG or the rule book.
You didn't ruin anything. Just weirdly pedantic for no reason
Weirdly pedantic is fun sometimes, and I'd say especially so with D&D 5e rules that often are very poorly worded.
Damage taken from being the Fall season would be called "Fall damage" in English though. It is not a verb that you did, it is a noun that is. You are not falling. It is fall. Falling is only from a present tense verb of fall.
