grammaticality
I have a sentence that I was supposed to correct; it wasn't hard to correct, but I couldn't help noticing the "yet" in the sentence: it sounded wrong, but I know that English is sometimes weird.
Here's the sentence:
We haven't had any snow yet this year. (I changed no to any)
The yet sounds weird in the sentence, almost unnecessary. I know that if I take out the yet, the sentence still works, but I'm wondering if it works if it's in.
It sounds fine to me. (But I'm not actually a native speaker, and Indian English does have a reputation for using the progressive a lot.)
This is how I interpret "I'm loving it". (I've put back the 'g' because writing lovin' is too folksy for me.) I also assume "it" refers to something particular, like McDonald's or the food there. Also, I think it helps to consider the analogous sentence "I'm enjoying it".
English certainly uses stative: I love chocolate, or I enjoy classical music. This expresses your position on something. But suppose I'm at a play/concert/movie, and someone asks me what I feel, during the event. I may say "I'm enjoying it" or "I'm loving it (at this moment / so far)". This seems perfectly natural to me, though perhaps not to native speakers everywhere.
There's also a difference between "I love it" and "I'm loving it". If you love chocolate, it only says what you feel when the issue of chocolate comes up, but if you are loving McDonald's, it implies that you're there right now and/or are actively engaged in thinking about it and loving it. (Just as "I'm enjoying classical music [right now]" means more than "I enjoy classical music".) Presumably, "I'm loving it" is a subtle suggestion that you too, like the speaker of the slogan, ought to be at McDonald's right now and actually get on with the act of loving it, not merely think of it as a nice place to visit from time to time. :-)
Yes, the sentence is grammatically correct; here is a syntax diagram (parse tree) for the sentence:

It does in colloquial English, and with the "yet" in place, the implication is both that typically there is snow in a given year, and that the author would have expected snow by this point in the year; removing the "yet" neither renders the sentence incorrect nor ungrammatical, but may well alter the meaning relative to the author's original intent.
