Origin of pester

1530–40; perhaps aphetic variant of empester, impester to tangle, encumber (though pester is found earlier than these 2 words) < Middle French empestrer to hobble, entangle < Vulgar Latin *impāstōriāre to hobble, equivalent to im- im-1 + pāstōri(a) a hobble, noun use of Latin pāstōrius of a herdsman or shepherd + -āre infinitive suffix (see pastor); aphetic form apparently reinforced by pest (cf. -er6)
