We were arguing in class if the noun ''sweety" existed. After looking it up in monolingual dictionaries I argued against its existance. The only spelling I could find was "sweetie".
What would you say?
That's because you're an old curmudgeon. I use it. Though rarely in writing, so it's hard to tell if I say it with the "ie" or the "y" pronunciation.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
My curmudgeonly father-in-law is a collector of antique bottles.....he has, for example, Bayer aspirin bottles dating back to 1899, not to mention old vinegar bottles, soda pop bottles, etc. Anyway, I actually hadn't realized how Mr. Ouisch and I had fallen into a routine of always referring to or addressing each other as "Sweetie" until one day during a visit to my father-in-law's home (he lives in Georgia, we live in Michigan - we only get to visit there maybe twice per year) when he emerged from the "bottle room" and grumbeld "Here - I saw these at an antique show and bought them as a gift because they reminded me of you two...." He held out two very old emtpy bottles of some long-ago discontinued soda pop called "Sweetie." "It's all you two ever call each other...." he then snorted and sort of rolled his eyes.
I would use sweetie but I am not sure I would go as far as arguing against the existence of sweety.
You can call someone "Sweety" because you can use any name you like. But as a noun, "She is such an old sweetie", the "sweetie" spelling is preferred.
Just be careful that, in writing, you don't call someone "Sweaty", and you should be OK.
