In Southern and Appalachian speech, oldest’un means the oldest member of a group - usually the oldest child, but it can just as easily describe the first cow in a herd, the oldest tractor on the farm, or anything with years and stories behind it. It’s a contraction of "oldest one," using the regional ’un ending for "one."
'Oldest’un' is another one that's a common one - you'll hear it out in the country.

Origin and Etymology
The ending -’un for "one" came into Southern and Appalachian English from Scots-Irish and older British dialects. Words like little’un and young’un were common by the 1700s. "Oldest’un" followed naturally, used first for the eldest child and later for anything that’s been around the longest - whether it walks, moos, or needs an oil change.

"Oldest’un" carries warmth and familiarity. It can describe people, animals, or even objects with history.
