My pet peeve is everyday and every day.

I read Free Republic every day.
Reading Free Republic is an everyday habit.

[Joe Marine 76]

How about “irregardless” as a pet peeve?

I hate the word irregardless whenever and whomever uses it.

My pet peeve is everyday and every day.

That, and those who insist on using the non-word "alot".

My pet peeve is everyday and every day.

My pet peeve is William Safire's---the pet peeve.

One of these days, ongana buy a dog and name him Peeve, so I can introduce him to my friends, in the thrill of indignation, "This is my pet, Peeve."---William Safire, On Language.

Two cheerful dogs grace our household, but in my imagination we also have a dog named Peeve. He is perpetually grumpy; complains about his dog food, collar is too tight, bed lumpy, not getting enough exercise, all that. What especially gets his hackles to rise is human language he doesn’t understand.---William Safire, "And Now This," The New York Times, 28 October 2008.

After lamenting the disuse of "the fine old airline verb" deplane, in favour of debark, Safire ended with this jewel: Have to go now; my pet, Peeve, is debarking.
