What does buist mean?
"Buist" is a Scots and Northern English dialectal form of "burst," meaning to break open, rupture, or give way suddenly — typically under internal pressure. It applies naturally to pipes, boilers, tyres, sacks, boils, and other things that split apart when they can no longer contain what is inside them, as in "the old cistern buist during the hard frost." The word belongs firmly to regional speech: while it remains part of living vernacular in Scotland and parts of northern England, standard British and American English use "burst" instead, so "buist" reads as distinctly local rather than formal or literary. Like its standard counterpart, it functions chiefly as a strong verb describing sudden, forceful failure, and it carries connotations of abruptness and sometimes damage or mess. For readers outside these regions it is best treated as a dialect curiosity; within them, it is an ordinary everyday word.
verbTo burst; to break or split open suddenly, especially of something swollen with pressure. In Scots usage it can describe anything from a boiler giving way to a boil bursting.

Etymology of buist
"Buist" is a dialectal variant of "burst," a native Germanic word going back to Old English "berstan," meaning to break suddenly. The Scots and Northern English forms reflect regular sound development in those dialects, where the vowel and consonants shifted from the standard southern line that produced modern "burst." It is therefore a cognate-within-English of "burst" rather than a separate borrowing, sharing its Old English root with related Germanic words such as Old Norse "bresta" (to crack).
How buist is actually used
This is a regional dialectal form found chiefly in Scotland and northern England; it would sound nonstandard in formal writing elsewhere, where "burst" is the expected form.
