Latin Ties Things Together With Abstruse

Look closely at the following Latin verbs, all of which are derived from the verb trudere ("to push, thrust"): extrudere, intrudere, obtrudere, protrudere. Remove the last two letters of each of these and you get 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 17th-century borrowing has fallen out of use. An abstrudere descendant that has survived is abstruse, an adjective that recalls the meaning of its Latin parent abstrūsus, meaning "concealed."
