As a noun, a tweet is a short message posted on the social media platform X (formerly Twitter). As a verb, to tweet means to send such a message, or to make a high, bird‑like sound.
Originally an echoic word imitating the sound of small birds. The tech meaning was popularized by the social network Twitter, which themed its brand around birds and chirping.
The word "tweet" jumped from birds to the internet, turning tiny bird sounds into tiny text messages. Even after the platform rebranded, people still say "tweet"—language changes slower than logos.
