身分

Appears to be a shift from older shinbun reading, replacing the on'yomi of shin for 身 with the kun'yomi of mi. First attested in 1688.^[1]

• (Tokyo) みぶん [míꜜbùǹ] (Atamadaka – [1])^[2]
• IPA^(key): [mʲibɯ̟̃ɴ]

身(み)分(ぶん) • (mibun) 

1. [from 1688] social position, social status, social standing

   いいご身分(みぶん)

   ii go-mibun

   good social standing

2. [from 1809] one's circumstances, one's condition
3. [from 1886] one's legal status, one's identity

• 身分相応(みぶんそうおう) (mibun sōō, “suitable, expected, within one's means or status”)
• 身分不相応(みぶんふそうおう) (mibun fusōō, “out of character, audacious, beyond one's means or status”)
• 身分証明書(みぶんしょうめいしょ) (mibun shōmeisho, “identification card”)

Borrowing from Middle Chinese 身分 (MC syin pjun|bjunH), modern Chinese spelling 身份 (shēnfèn). First attested in Japanese in 984.^[1] Superseded by the mibun reading starting from the late 1600s. The shinbun reading is included in a dictionary published in 1874,^[1] but it is not included in most modern references.^[3][2][4][5]

• IPA^(key): [ɕĩmbɯ̟̃ɴ]
