Forms

ūni-[1] Before a vowel it appears as ūn- (ūnanimus).[2][3]

Etymology

It is from Latin ūnus (“one”), the form the numeral takes as the first part of a compound.[1][2] The OLD explains each such compound from the numeral and the second word (ūnicornis “one-horned” from the numeral and the word for horn).[3]

Earliest recorded meaning

Plautus (c. 250–184 BC) has ūnisubsellium, a bench for one person, and ūnoculus “one-eyed”.[3][4]

Semantic evolution

Pliny the Elder has a series of descriptive adjectives such as ūnicaulis “with a single stem”, ūnistirpis “with a single trunk” and ūnicornis “with a single horn”, and inscriptions praise a wife as ūnivira, one who has had only one husband.[3]

English took uni- with many words borrowed from French and Latin; it was not active in Middle English, and its use with English words became established in the 19th century.[2]
