I suck at vowels. Is it mentOr, mentEr, or mentAr. Donor rhymes with loaner, but spelled different. Bugger off English. Sensible and noticeable...same frigging rhyme but nope, different spelling. Of course, it may just be the drawl. Some of them erudite professors may say them differently.
There is an example of how how a words meaning changes over time.
Frigging is an old term which means a female masturbating..
