"I think in English this never happens as unlike Hebrew, I can't think of a letter than can act as a meaningful prefix." a on its own can be a few different prefixes: https://www.etymonline.com/word/a-?ref=etymonline_crossreference#etymonline_v_24553 https://www.etymonline.com/word/a-?ref=etymonline_crossrefer...

I certainly agree I've never thought of this in the context of a word game, as opposed to the s suffix which is almost mandatory in Boggle, for instance.
