neutraldaily actionswork

How it's used

Carries a strong sense of unauthorized or secretive action, often implying that the person doing the action has overstepped their boundaries. It is frequently used in formal or serious contexts to describe rule-breaking behavior, though it can also appear in daily speech when someone is annoyed by a lack of consultation.

Common phrases

to act without authorization
to decide on one's own without consulting others

Common mistake

Do not confuse this with 私下, which simply means privately or between two people without involving others. While 私下 is neutral and often implies discretion, 私自 carries a negative connotation of acting against rules or ignoring authority.
