Which is correct out of the following...?

The person is the grocer. The shop is strictly the grocer's because it implies "grocer's shop". Many people refer to the shop as a grocery and this is common parlance now, even though grocery is strictly the act of selling groceries rather than the place they are sold.

I think you could almost get away with grocers as well, because the shop is implied but not often written. You would only ever use grocers' to refer to grocers' shops (where there is more than one grocer and more than one shop).

Is it me or has the word gone weird now. Grocer's. Grocer, Grocery. Its Gross.

Man I really hate the word greengrocer. Yuck!

Lol at spotty. "At your grocer's freezer." There's an example of that one, but yeah, everything dappled said is right.

Supermarket. Tesco. ASDA. Bless the long forgotten Grocer at his Grocer's selling his Groceries. I still go to the Butchers and not the Butchery.

The Grocery store.
Simple. Uncomplicated.
Or, the Market. Though I never say that, just the Grocery store.

grocererier is the correct term for the seller and groceratorium is the shop, its just a shame people dont use proper english any more

"Grocer's" would mean an area owned by a grocer, a person who sells groceries.
