obstreperus

Latin

Etymology

From obstrepere, present infinitive of obstrepō (“roar, resound; clamor; annoy; make a noise against”) + -us.

Note: This represents an unusual and somewhat unique Latin formation, as the adjectival suffix is amended to the infinitive form of the verb. This is opposed to the suffixation of the first person present indicative, as is the usual custom when adjectives are created from verbs in Latin; such is the case with dīvidus and prōdigus, for example. This application serves to emphasize the universality of application of -us in the creation of adjectives.
