Fun Fact: Learnt is a word used by mostly British people (such as myself) and is absolutely a word.
Still 20 over in NW VA
"Learnt" is a word back in the hills where you're at too, Max, but the expansion of Washington/Baltimore metroplex drove most of the native speakers south and west. You'll often hear it during the high water seasons. "She tried to drive her car through the underpass, but she learnt better about 15 foot in."
The difference between "foot" and "feet" can be confusing. Everyone knows humans have two feet and most other land mammal's have four, but foot can refer to distance, a measure, or part of your body in the uplands of the Virginia's. "Give me 50 foot of RG-8 coax." will get you what you want, while, "Do you have 50 feet of RG-8 coax.", says, "This guy ain't from around here. Tack 50 cent's a foot on to the price and let's see what else we can squeeze out of him? He ain't learnt our ways yet."
