Ta-Nehisi Coates talks to Jesse Sheidlower, editor at large of the OED, about what words are really words. Turns out they all are — it’s just that some aren’t appropriate in certain instances:
“Table” is generally acceptable, but “ass” or “fuck” might not be, In some cases they would. It’s the same for “hopefully” or “irregardless.” They’re all words, but it behooves us to be serious and ask, is it acceptable in this context? If you’re delivering the State of the Union address, maybe “fuck” is not acceptable. If you’re having sex with your girlfriend, maybe it is acceptable.
Also, on the question of “aks”:
But if you look at the history of the English language, you can’t tell if the correct pronunciation is “aks” or “ask.” The “aks” pronunciation goes back 1000 years. It’s in Beowulf. It’s in Chaucer.
What happened was both were in use. But at some point, the dialect in which the “ask” pronunciation was used became dominant. But both continued and have been in use since then. When you look at America, the “aks” pronunciation is widespread in Southern American English. African-Americans used this because they were in the South—it’s not especially African-American, but it’s Southern.
