Forms
dēnseō (present infinitive dēnsēre); second conjugation, no perfect or supine stems[1] Lucretius has the passive infinitive dēnsērier.[2][3] Charisius gives a perfect dēnsī.[3] Manuscripts often confuse it with dēnsō.[2]
Etymology
It is from Latin dēnsus (“thick”) + -eō.[2][1][3] De Vaan traces dēnsus to Proto-Indo-European *d(ē̆)ns-o- (“thick”) and dates this verb from Lucretius, beside dēnsō, found from Ennius.[4]
Earliest recorded meaning
Lucretius has it first,[4] saying that air can be condensed.[2]
Semantic evolution
It is to thicken or condense: Lucretius has heat that weaves clouds over the blue, Virgil darkness thickening with the night, and Ovid a sky made thick by a spell and a comb that closes up a loose weave.[2][5] It is to crowd together: Virgil has columns massed on the plains, Sallust a front strengthened with reserves, and Calpurnius a pine wood thick with foliage.[2][5] It is also to make things come thick and fast: Virgil has spears hurled one after another, Horace the funerals of old and young crowding together, and Tacitus blows struck fast.[2][5] Macrobius has a body made dense by natural cold, and Ammianus a close wall of shields.[5]
