oncet pronunciation

/WUNST/

Meaning

Oncet means once. Southern and South Midland speakers often add a final t to once and twice, so you get oncet and twicet. Same idea as acrost for across. It is everyday redneck and mountain talk, not a joke spelling. You'll hear it in church stories, farm talk, and anybody who says they try to read the Bible through oncet a year.

How folks use it

  • “I only been there oncet, but I ain't forgettin' it.”
  • “He figured he'd rode around the world onst and a half.”

Origin and etymology

Excrescent final t on once. Noted in Tennessee dialect writing by 1891 alongside twicet and acrost. Dictionary of American Regional English labels the pronunciation chiefly South and South Midland. Kurath and McDavid found the added t on once and twice across the Midland and South, even among some middle-class speakers.
