adverb taking the 'to' particle, adverb
Describes a state of doing nothing productive, moving slowly, or lacking purpose. Often used with と (to) as an adverb. Rare and literary; not common in everyday speech.
彼は日がな一日べんべんだらりと過ごしている。
He spends the whole day idly.
べんべんだらりとした態度が上司の不興を買った。
His sluggish attitude incurred his boss's displeasure.
Means evasively or lazily avoiding work. べんべんだらり focuses more on aimless idleness without the nuance of evasion.
Compound of 便便 (benben, 'idle, at ease') and だらり (darari, 'loosely, languidly'). The exact historical derivation is uncertain, but it is a literary reduplicative phrase.
