To announce means to make something known publicly or officially. It can be done by speaking, writing, or using media.
From Latin 'annuntiare' or 'annuntiare' meaning 'to report' or 'to give notice', from 'ad-' (to) + 'nuntius' (messenger). The word traveled through Old French into English.
The root is about messengers, which is why we also have 'enunciate' (to speak clearly) and 'pronounce'. Every announcement is a tiny act of power: choosing what becomes public and what stays hidden.
