Harsh or unpleasant in sound; discordant or disagreeable to the ear.
From Latin 'absonus,' a variant of the same root as 'absonant' (ab- 'away from' + sonus 'sound'). This is an archaic or poetic variant of the more common 'absonant.'
Both 'absonant' and 'absonous' are extremely rare—they're basically fossil words from when English writers loved inventing Latin-based terms for sounds. You'd impress any classics professor using one!
