In Ancient Greek grammar, a perispomenon is a word with a circumflex accent on the last syllable. A properispomenon is a word with a circumflex on the second-to-last syllable.[1]
Peri-spṓmenon means "pronounced with a circumflex",[2] the neuter of the present passive participle of peri-spáō "pronounce with a circumflex" (also "draw off").[3] Pro-peri-spṓmenon adds the prefix pró "before".[4]
