Grammar question, please help?

1. "I like chocolate". This refers to the substance in general, as well as the flavour. "I like chocolates" means you like the little chocolate sweets/candies that come in boxes.

2. "I like ice-cream" if you mean the substance.

3. "I want to buy some ice-cream" if you mean any form of it. "I want to buy some ice-creams" if you want to buy a collection of separate ice-cream items (such as cones, wafers, or tubs).

I like chocolate.

I like ice cream.

I want to buy some ice cream.

For "ice-cream," it is a noun that, conventionally, can be singular or plural, although the singular form sounds better, in my opinion. So, "I like ice cream" can mean you like ice cream in general. It could mean you like one or many flavours.

As for "chocolate," it usually refers to the flavour. If you like the chocolate flavour, you should say "I like chocolate." On the other hand, if you are saying you like chocolate in general, you should say "I like chocolates." There actually isn't a specific rule dictating when you should use either forms. It really is a matter of preference.

Overall, I think using the singular forms sound better as they are more commonly used.
