Did You Know?
Look closely at the following Latin verbs, all of which are derived from the verb "trudere" ("to push"): "extrudere," "intrudere," "obtrudere," "protrudere." Each of these Latin verbs has an English descendant whose meaning involves pushing or thrusting. Another "trudere" offspring, abstrudere, meaning "to push away" or "to conceal," gave English abstrude, meaning "to thrust away." But that verb didn't make it past the 17th century. The "abstrudere" descendant that did survive is "abstruse," an adjective that recalls the meaning of its Latin parent abstrusus, meaning "concealed."
