Keep your word

I think I said I was going to write about war. So here goes.

WAR WARN WARM WARMTH WART SWARM SWARTHY WARBLE WARD WARP  SWARD

Should I add WHARF and QUARTET?

These are all words where "w" makes "ar" say "or."

Then there's the other kind of war, where "or" says "or," the "w" having no effect.

WORE WORN SWORE SWORN WHORL

And then there's the kind where "or" doesn't say "or," but neither is there any war involved, such as WORM WORD WORK...

Okay, I better quit.
