In Appalachian and Southern speech, "mightnotta" means "might not have."
It’s a natural contraction that blends the words together in quick talk, the same way folks say "shouldn’ta," "wouldn’ta," or "couldn’ta."
"I mightnotta fed them chickens this mornin’ - can’t recollect."
That’s how we talk when a thing’s half-forgotten and maybe didn’t happen.

Origin and Etymology
Formed by blending "might not have" into one smooth phrase.
Southern and Appalachian speakers naturally drop the "have" and soften the sounds, giving "might-not-have" → "might-not-a" → "mightnotta."
It follows the same pattern as "wouldn’ta" and "shouldn’ta," all shaped by everyday speech rhythm.
Usage Notes
"Mightnotta" appears mostly in conversation or dialogue writing meant to sound true to life.
It carries a relaxed, uncertain tone - something between a confession and a shrug.
"I mightnotta told her yet." → I may not have told her.
Yes, especially in rural Southern and Appalachian speech - many folks say it without realizing it’s non-standard.
Where did it come from?
From the natural reduction of "might not have," the same pattern found in "shouldn’ta" and "wouldn’ta."
