Sense: verb/1
All three phrases describe saying something suddenly, but they differ in tone and control. 'Blurt' (or 'blurt out') emphasises a lack of self-control—you say something impulsive before your brain can stop you. 'Let slip' is less about impulse and more about accidental disclosure; the speaker might have been careless rather than explosive. 'Burst out' is the most emotional, often used with laughter, tears, or angry words ('She burst out crying'), not just information. For example: 'He blurted out that he loved her' (impulsive confession). 'She let slip the party plans' (accidental reveal). 'They burst out laughing at the joke' (uncontrollable emotional reaction).

Etymology
The origin of 'blurt' is uncertain. It first appeared in English around the 1570s, possibly created as an imitation of a sudden, explosive sound (like a cough or a sputter that forces words out). Some linguists think it may blend 'blare' (a loud sound) and 'spurt' (a sudden burst). The meaning has stayed very close to this sound-image: words that burst out of the mouth without control.
