Unauthorised Meaning in English

word

Definition

Not having official permission or approval; not allowed by authority.

Usage & Nuances

Mainly used in formal or legal contexts for actions or access lacking official approval (e.g., 'unauthorised access,' 'unauthorised person'). Not synonymous with 'illegal,' though they may overlap; 'unauthorised' focuses on absence of permission, not always criminality.
