Makes a loud, sharp, high-pitched sound that is often unpleasant or alarming.
From Middle English 'scrichen,' possibly imitative (imitating the sound). Related to Scandinavian words with similar sounds. It's an onomatopoeia.
Screeching is an evolutionary alarm signal—our brains are hardwired to respond to high-pitched sounds because they often meant danger to our ancestors. That's why nails on a chalkboard bother us: it mimics predator warning calls our ancient brain still fears.
Screaming and screeching have been stereotyped as 'hysterical' feminine behaviors since the 19th century, creating bias against women's vocal expression of distress or anger.
Use 'screeches' neutrally for any person or animal; avoid pairing with gendered descriptors like 'hysterical' or 'shrill.' Acknowledge all genders express intensity vocally.
