わんぱくな

わんぱくな
adjective
naughty; mischievous; rambunctious
1. naughty, mischievous, rambunctious
Describes a child who is energetically disobedient, playfully unruly, or boisterously active. Generally carries an affectionate or tolerant nuance rather than true disapproval.
わんぱくな子供(こども)だ。
He's a naughty kid.
うちの息子(むすこ)はわんぱくで(こま)っている。
Our son is so mischievous, it's a handful.
わんぱくな(おとこ)()たちが公園(こうえん)(どろ)だらけになって(あそ)んでいた。
The rambunctious boys were playing in the park, covered in mud.

Also written in kanji as 腕白(わんぱく), though the hiragana or katakana spelling is more common today. Typically used to describe boys, though it can apply to any energetically mischievous child. The word has a warm, almost nostalgic tone — it suggests healthy, spirited playfulness rather than malicious behavior.

USAGE:
Functions as a na-adjective (わんぱくな()) or as a noun (わんぱくを()う, わんぱく坊主(ぼうず)). Almost exclusively used for children — using it for adults would sound odd or deliberately humorous.

  • わんぱく(ざか)り: at the peak of mischievous age
