na-adjective, noun
boorish; uncouth; tasteless; insensitive
Describes a person, remark, or behavior that lacks refinement, social grace, or sensitivity to the atmosphere. Often used for someone who is oblivious to subtlety or says something tactless. The antonym is 粋 (いき), meaning stylish or chic.
Antonyms: 粋 (いき)
彼の野暮な質問で場がしらけた。
His tactless question killed the mood.
Don't say such boorish things.
The exact origin is uncertain. The kanji 野暮 are ateji (phonetic) and do not contribute to the meaning. The word may be related to 野 (rustic) and 暮 (living), suggesting a lack of urban sophistication, but this is speculative.
