also: ずべら
na-adjective, noun
Describes a person who is habitually careless, untidy, or lazy about chores, appearance, or responsibilities. Often used self-deprecatingly or to gently criticize someone's laid-back attitude.
彼は掃除が面倒で、ずぼらな生活を送っている。
He finds cleaning a hassle and leads a sloppy lifestyle.
私はずぼらだから、いつも部屋が散らかっている
I'm so slovenly that my room is always messy.
だらしない emphasizes a lack of discipline or self-control, often implying moral weakness, while ずぼら focuses more on laziness or carelessness in daily habits.
怠け者 is a straightforward noun meaning 'lazy person,' whereas ずぼら can be used as an adjective or noun and carries a nuance of being sloppy or negligent rather than purely lazy.
The origin is uncertain. It may be related to the mimetic word ずぼり (loose, baggy) or the dialectal ずべら, but the exact derivation is unclear.
