I have blogged about my peevishness over the conflation of these two words before. I have often vowed, with rare irresistible exceptions, not to purchase from vendors who don't know how to spell their own stock.
But now I see the search results on etsy, and I wonder if I need to mistakenly tag my items with "stationary." I think more people search for "stationary" than "stationery." ARRRRGH!!
I mean, is a postcard really meant to be stationary? I think it's meant to fly...
Apologies for the late-night rant. I think I won't respect myself in the morning if I cave. Persnickety grammarians will agree, and the rest of you will probably think we're just fuddy-duddies. Ah well. Perhaps we are.
