noun
unregistered; unreported; not filed
Used for a status such as a marriage, business, or procedure not having been reported or registered. This sense as a confusion with 未届け; in careful writing, 未届け is often the more precise form for 'not yet reported/filed,' while 無届け emphasizes doing something without the required notification.
無届けの営業が問題になった。
The unreported business operation became a problem.
その書類では、婚姻が無届けのままだと説明されていた。
The document explained that the marriage remained unreported.
Means 'not yet reported/filed' and is the form As being confused with 無届け in the unregistered or unreported sense.
Means 'without permission' more broadly; 無届け specifically focuses on not submitting the required notice or report.
Means a notification or report submitted to an authority; 無届け means that this required notification has not been made.
Formed from 無, meaning absence or lack, plus 届け, a notice, report, or filing. The spelling transparently conveys 'without a notification/report.'
