乸

Probably a dialectal form of 女 (OC *naʔ, “woman; female”) (Schuessler, 2007).
Alternatively, Li (1990) proposed that this may be a Tai substrate loan, related to Zhuang nax (“younger maternal uncle or aunt”), Thai น้า (náa) (which go back to Proto-Tai *naːꟲ (“mother's younger sibling”)).

cog

(Cantonese, figuratively, of instruments, tools, or connectors) female


鳩

→? Proto-Hmong: *ɴquᴬ (“pigeon”)

/t͡ɕi̯oʊ̯⁵⁵/

/t͡ɕi̯oʊ̯⁵⁵/

Phono-semantic compound (形聲 /形声, OC *ku): phonetic 九 (OC *kuʔ) + semantic 鳥 (“bird”).
From Proto-Sino-Tibetan *m-k(r)əw (“dove, pigeon”) (Benedict, 1974; Schuessler, 2007; STEDT). Compare Tibetan འང་གུ ('ang gu, “pigeon”), Proto-Loloish *m-krəw², Burmese ချိုး (hkyui:), Proto-Kuki-Chin *khruu.
In some southern Chinese dialects, 鳩 /鸠 is pronounced with aspirated initial /kʰ/ due to taboo considerations.
