Way back to jan Mato's list: I note that none of them actually has a way of saying bend or fold or turn but only various ways of getting to the result (a doubled shirt, a change of direction, etc. I haven't quite figured out how we got off on dirty hair ("Make my da") (bend > curl > hair > straight > stick > sticky?) but it doesn't seem to be getting anywhere. The wisdom of avoiding the issue will only last until we get to a case where we can't and want to talk about the actual activity of bending (etc.) and then, given our resources, we have , I think, to work with 'sike' (the only shape word we have) and get "straight" out of that, too.
