noun
A somewhat literary or formal term for the countryside, often with a nuance of remoteness or rusticity. Not the most common everyday word for 'countryside' (that would be 田舎).
鄙の地で静かに暮らしたい。
I want to live quietly in a rural area.
鄙びた温泉宿に泊まった。
We stayed at a rustic hot-spring inn.
田舎 is the standard, everyday word for 'countryside' or 'hometown'. 鄙 is more literary and emphasizes remoteness or rusticity.
The kanji 鄙 originally meant a remote village or rustic area. The reading ひな is a native Japanese word for countryside or rural area, possibly related to ひな (small, doll-like) suggesting something small and remote. The exact derivation is uncertain.
