Historical forms of the character 烏
Western Zhou	Shuowen Jiezi (compiled in Han)
Bronze inscriptions	Small seal script

Pictogram (象形) – a bird. Compare 鳥 (“bird”), of similar development. See also the original version of its variant 於.

“crow; black; dark”

From Proto-Sino-Tibetan *ka-n (“crow”) (STEDT). Doublet of 鴉 (OC *qraː, “crow; raven”), which retains the earlier vowel in Middle Chinese (*ʔˠa), and 鸒 (OC *la, *las, “jackdaw”).

Schuessler (2007) considers it to be onomatopoeic, and compares it with Proto-Loloish *akᴸ (“crow”).

“Black; dark” is a semantic extension of “crow” – “black as a crow”. Compare 黑 (OC *hmlɯːɡ, “black”), which is cognate with 墨 (OC *mlɯːɡ, “ink”).

“sun”

The Three-legged crow was thought to reside in the Sun.

interrogative pronoun

Related to the following interrogative pronouns with similar phonological shapes in Old Chinese (Wang, 1982), with differing suffixes:

• 焉 (OC *qan, *qran, “how; where”)
• 惡 (OC *qaː, “how”)
• 安 (OC *qaːn, “where; how; why”)
