Etymology 2

Alternative spellings
波布飯匙倩

Borrowed from Okinawan 波布 (habu, “pit viper”), where this kind of snake is native. Appears to be cognate with Japanese 蛇 (hebi, “snake”, depending on dialect, hebi may refer specifically to non-venomous snakes), and related to verb 食む (hamu, “to bite”).[4]

First cited in Japanese to a text from 1795.[5]

Pronunciation

(Tokyo) ハブ [háꜜbù] (Atamadaka – [1])[3][6][7]
IPA^(key): [ha̠bɯ̟ᵝ]

Noun

ハブ • (habu)

波布, 飯匙倩: Trimeresurus flavoviridis (now Protobothrops flavoviridis), a species of venomous pit viper native to Okinawa

Etymology 3

Shortening of noun form 省き (habuki, “omission”), in turn from verb 省く (habuku, “to omit”).[8]

Pronunciation

IPA^(key): [ha̠bɯ̟ᵝ]

Noun

ハブ • (habu)

(informal) someone who is left out of a group

Usage notes

May be used in a verb construction as ハブにする (habu ni suru, “to leave out of a group”, literally “to treat as an omission”).[8] Alternatively, the derived verb ハブる (haburu) may be used instead.[9]

Synonyms

のけ者(もの) (nokemono)
仲間外(なかまはず)れ (nakamahazure)

Derived terms

ハブる (haburu)
