commo

The informal noun 'commo' is a 20th-century military and political slang term with two distinct but related origins. Its primary meaning, "a fellow soldier," is a clipped form of 'comrade,' a word borrowed from French and Spanish, ultimately from Late Latin 'camerata' meaning "chamber mate." Its secondary, politically charged meaning as "a communist" is a direct shortening of 'communist,' which derives from Latin 'communis,' meaning "common, public, shared by all." The term's dual usage reflects its evolution within the specific, often overlapping, contexts of military camaraderie and ideological affiliation, where brevity is valued.

This word is a clipping (shortening) of the longer words "comrade" or "communist." It is not formed from productive morphemes in modern English and therefore cannot be meaningfully segmented based on its current spelling.
