Re: Games similar to "Say Anything" or others that help practice English
I wouldn't recommend Codenames, since language skills are essential there. Better-skilled people will dominate the game, and the ones who want to learn sit there and say nothing.
Any cooperative game should be fine. Take "The Game" for learning numbers and synonyms for smaller or greater differences. We own "Hanabi" which is also fine. I wouldn't recommend either with more than 4 players, though. If learning the language is the focus, more players aren't better, anyway, since the weaker speakers will automatically talk less. For more advanced gamers, take "Robinson Crusoe" or any other cooperative game of your preference.
