Behavioral therapy.

There's nothing in the rules about that, and that's why I'm saying it's just desirable to think about other players. But in principle, no one does that :D. And "A" isn't even a word. And only one word can be formed from that letter: Iakshat'sya.

First, try to come up with something that will make it more difficult for the next player to respond;
Secondly, "A" isn't relevant here... because the first word wasn't an adjective ;) So this example isn't entirely appropriate :)
Thirdly, if there isn't a suitable word, you can suggest a similar one, even a synonym. You can even find something similar starting with "A" (since you're tired of words starting with "A"): A -> Alpha -> Alphatic... It's more about the next player ;) :)
