cervus

• cervos

From Proto-Italic *kerwos, from Proto-Indo-European *ḱr̥h₂wós, from *ḱerh₂- (“horn”) (whence English horn, hirn, Latin cornū (“horn”)) + *-wós (whence Latin -vus).

Cognate with Welsh carw (“deer”), Greek κεραός (keraós, “horned”). The first-syllable e was likely taken from the PIE root noun *ḱerh₂s (“horn”) (itself eventually lost in Latin), while the shift in meaning from 'horned' to 'deer' may be common Italo-Celtic.^[1]

• (Classical Latin) IPA^(key): /ˈker.u̯us/, [ˈkɛru̯ʊs̠]
• (modern Italianate Ecclesiastical) IPA^(key): /ˈt͡ʃer.vus/, [ˈt͡ʃɛrvus]
