"Behooves"

       I was curious about the word "behooves" because of its sound, and it took me on this journey:

       Behooves means to "be morally required of (a person), be incumbent upon; befit."  It behooves one to do this, we say.

       It is derived from Middle English behoven, from Old English behof "use, profit, need," thence from Germanic bi-hof:  "bi" is a reduced form of ambhi from Indo-European "on all sides" and is an intensifying prefix; so what is at root here is "to have a need all around"; "that which binds."

       If it "behooves" you to do something,  everything is pointing towards its necessity!
