israeli sign language: you can sign climbing a tree by one hand signing "tree", a sign that conveniently kinda looks like a tree, and having the other hand go up next to/on top of the other. when the story tells about coming back down, the hand that climbed up now goes back down
hebrew: if i'm telling a story about climbing a tree, i will increase my pitch to signify going up. when the story tells about coming back down, i'll decrease my pitch to signify going down
heck, the hebrew verb for "to roll" is most likely a gosh dang onomatopoeia!! like,,,, dude!! iconicity in language is all over the place and all around us and it's friggin awesome!!!
