Every once in a while, I drop in to Language Log to see what is occupying the minds of some of the more energetic linguists amongst us. The posts can be quite topical and informative, such as the distinction between Myanmar and Burma. A few of the more patient contributors answer questions posed by their comparatively less educated readers. One such recent response left me completely mystified. I could not detect an answer within the answer but I did come across the phrase "gotten commoner."
This is common 21st century English usage?
(By the way, if anyone discovers the answer to the original question within that answer, please let me know.)
