Etymology

It is from Latin ūmeō (“to be wet”) according to de Vaan, who lists it among that verb's derivatives.[2] The OLD analyses it as a stem ⟨ūl-⟩, which it compares with ūdus (“wet”) and with that verb, and the suffix -īgō.[3] Lewis & Short and Wiktionary explain it instead as a contraction of ⟨ūvilīgō⟩, from the family of ūvidus (“damp”).[4][1] The verb goes back to Proto-Italic *ūmo- (“wet”) and Proto-Indo-European *uh₁-mo- (“wet”).[2]

Earliest recorded meaning

It is found from Cato on,[2][5] meaning waterlogged ground.[3]

Semantic evolution

In Classical Latin it is the natural dampness of the soil and marshy ground, in Varro, Columella, Virgil, Silius Italicus and Tacitus;[4][3] Servius comments on Virgil's use of it.[4]

In British Medieval Latin it meant a marsh or bog, and also a jelly-like substance found on wet ground, popularly called a “fallen star”.[6]
