Forms

poscō (present infinitive poscere, perfect active poposcī or peposcī); third conjugation, no supine stem[1]

Etymology

It is inherited from Proto-Italic *pork-ske/o-, inherited from Proto-Indo-European *prḱ-sk-e/o- (“to keep asking”), a present in *-sk- of the root Proto-Indo-European *preḱ- (“to ask”).[2][1] Cognate with Umbrian pepurkurent (“they will have demanded”), Sanskrit पृच्छति (pṛcchati, “asks”) and Old High German forskōn (“to search”).[2][3][4] The same root is in prex “prayer”, precor “to pray” and procus “suitor”.[3][4] Schrijver doubted whether the vowel is regular for *pr̥ksk-, since Oscan comparascuster may show *parksk-.[2]

Earliest recorded meaning

De Vaan dates it from Plautus.[2] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

It meant to ask for insistently or with authority, to demand, with a double accusative to demand something of someone, and to summon, as Virgil's suppliant who calls on the gods.[3] Plautus uses it of asking a girl in marriage and of bidding at an auction.[3] Of things it meant to require, as what the times of the republic demanded.[3] Döderlein places poscere at the demanding end of a scale that runs through petō and rogō to ōrō, the humble request.[6]

In medieval grammar it was used of a verb that requires a case.[7]
