From translingual Vireo (genus name), from Latin vireō (“I am green”).
vireo (plural vireos or vireoes)
The alternative plural form vireoes appears to be relatively rare and dated.
Unknown. The LIV suggests that it derives from a PIE verb *wis-éh₁-ye-ti, from a root *weys-, perhaps whence also Lithuanian veisti (“to breed, rear”). Moreover, the term has been connected with Old Norse vísir (“sprout”), and 古期英語 wīse (“sprout, stem”). If this comparison is accepted, the terms could all be attributed to a PIE root of the shape *weys-. However, De Vaan rejects all of the proposed cognates on semantic grounds.
vireō (present infinitive virēre, perfect active viruī); second conjugation, no passive, no supine stem
