ex-

Forms

ex- (also ē-, ef-, ec-)^[2][3]

Etymology

It is inherited from Proto-Italic *eks (“out”), inherited from Proto-Indo-European *h₁éǵʰs (“out”), the preposition ex used as a preverb.^[3][1][2] Before voiced consonants Latin has ⟨ē-⟩, from ⟨*egz-⟩, and before ⟨f⟩ ⟨ec-⟩, usually assimilated to ⟨ef-⟩.^[3]

Cognate with the preverbs Oscan eh- and Umbrian ehe-, Old Irish ess- and Ancient Greek ἐξ (ex, “out of”).^[3]

Semantic evolution

In compounds it means “out” or “away”, “throughout”, “thoroughly”, the achievement of an aim (as in expugnō and exōrō), and “up”; with nouns it can also be privative, as in exsanguis “bloodless”.^[2][1]
