Forms

pinguēscō (present infinitive pinguēscere); third conjugation, no passive, no perfect or supine stems[1] No perfect forms are attested.[2] A spelling pinguīscō occurs in the Old Latin Psalms and in Venantius Fortunatus.[2][3]

Etymology

It is from Latin pinguis (“fat”) + -ēscō, an inchoative verb.[4][5][2][1] De Vaan rejects the etymologies proposed so far for pinguis and finds it semantically most attractive to connect it with Proto-Indo-European *piH- (“to increase, be abundant”), the root of Lithuanian píenas (“milk”);[6] Latin ⟨pin-⟩ could then come from an n-stem, but the element ⟨-gui-⟩ remains unexplained.[6]

Earliest recorded meaning

De Vaan records it from Lucretius on,[6] who says that hemlock often fattens bearded goats, pinguēscere saepe cicūtā barbigerās pecudēs.[4] The TLL finds it once each in Lucretius, Virgil and Ovid, and then from Seneca's prose on.[2]

Semantic evolution

Virgil uses it of the plains of Haemus grown rich twice with “our blood”, and Ovid of fattening a body on another body.[4][5] Columella has lean cattle fattening on lucerne, and Pliny the Elder uses it widely: of a fish that grows to a thousand pounds through idleness, of fields made fertile, of wine that gains body with age, of walnuts that grow oily, and of a stone that takes on an oily sheen when polished.[4][5] In Silius Italicus flames grow stronger, and Martial has hair glossy with balm.[4][5]

Grammarians used it of sounds: one of a letter that sounds full in pronunciation, Sergius of the Aeolic Greeks adding a digamma to some words.[4][5] In Ecclesiastical Latin it means to grow fat and to become fertile.[7]
