tweeting

Tweeting is posting short messages on the social media platform Twitter (now X).

The term borrows from the chirping sounds birds make—short, quick vocalizations.

A tweet is a single post; to tweet is to post one: She tweeted about the concert, He's always tweeting his opinions.

The word has become somewhat generic for posting brief updates on any social platform, though it originated specifically with Twitter's 140-character (later 280-character) format.
