Where do you look to see the ancient roots of English verbs? I love this history, because it makes the richness of words so much fuller and deeper, but I never know where to find the actual information on the historical root and usage. For example, "to Yield", as in give right of way, to yield, as in surrender during combat, or to yield, as in from a crop. I know this is an ancient word and I want to know where it comes from!
