What does sibilous mean?
Sibilous describes a sound that hisses or whistles, especially the sharp sounds produced by sibilant consonants such as s, z, sh, and zh. The word is more literary and descriptive than everyday: a sibilous wind may whisper through grass, while a sibilous voice may have a piercing, hissing quality. In linguistics and phonetics, it can refer specifically to sounds characterized by turbulent airflow through a narrow channel, which creates strong friction. Although the more familiar adjective is sibilant, sibilous emphasizes the audible, often piercing quality of the sound itself. Together with related terms such as sibilance and sibilation, it belongs to a useful vocabulary for discussing whispering, whispering noises, and the distinctive articulation of certain consonants.
