I already looked it up, I am just curious if people mostly see the word the same way. I hadn't paid attention to this one, I just write 'thank you' because that's what I thought my spellchecker was teaching me. Then I decided to look it up. The answer makes sense, but why wouldn't such a common word as the noun, thankyou, be in the spellchecker? It's not in Word, Scrivener or the forum spell checkers. Before I add it, I thought I'd see what other people here know about the word(s).
I never knew that the noun was one word. I always thought of it as "a thank you." Most often, though, I use the "thank you" as an adjective if I am not using it as a verb -- as in "I wrote him a thank you note." I want to put a hyphen in that thank you to make thank-you note, but I don't know why. I've no idea whether that would be correct and I am too lazy to look it up.
Thankfully, I don't have to deal with this word's evolution. It still looks very wrong to write them together like that.
I've seen it most often in its plural form, thankyous, which spellcheck is also balking at just now as I type it.
I tried 'thankyou' as a noun in a sentence, I tried it preceded by 'a', and I tried adding the 's' in all three word processors and all three got redlined. Bing and Google both look for "thank you note" when I search for "thankyou note". I think I'll stick to the two words and not add 'thankyou' to my spell checker. Thanks for everyone's input.
The Concise Oxford English Dictionary lists "thank you" (with the space) as both a verb and a noun. The New Fowler's Modern English Usage allows thank-you as a noun, but insists on the hyphen.
I don't think that "thankyou" is an accepted word yet. It may be on its way, but I wouldn't be surprised at any source objecting to it. I would definitely see it as an error.
. A big 'thankyou' to you all. To begin, may I thank you for... Who's dishing out the thankyous after the speeches? And thank you, too! Supremely often, what do spellcheckers know, particularly when it's UK vs. US English?
Spellchecker or not, these are some logical examples where one word does appear more correct. I think that's why I sometimes don't like how it looks on paper or the screen.
