The word consists of 'un-' and 'widerruflich' (revocable). 'Widerruflich' is derived from the verb 'widerrufen' (to revoke), which means 'to take back' or 'to cancel'. So 'unwiderruflich' (irrevocable) describes a state that can no longer be taken back.
Seine Kündigung ist unwiderruflich.
His resignation is irrevocable.
This word is often connected with decisions, consequences, or the end of something. Typical phrases are 'eine unwiderrufliche Entscheidung' (an irrevocable decision), 'unwiderruflich verloren' (irrevocably lost), or 'unwiderruflich vorbei' (irrevocably over).
Die Zeit unserer Kindheit ist unwiderruflich vorbei.
The time of our childhood is irrevocably over.
'Unwiderruflich' (irrevocable) is a formal word that is often used in legal and administrative language. It emphasizes the finality and binding nature of an action or state.
