Uncountable nouns

There is a large group of nouns in English, which cannot be counted. For example, we can say luggage, but not one luggage, two luggages, three luggages. That is why we call them uncountable nouns.

The following is true for them:
- They have no plural form (informationS porkS, furnitureS),
- There is no “a” or “an” in front of them (a pasta, a cheese, an advice),
- The verb in front of them is in the singular, like with he/she/it (My luggage IS heavy; The ice-cream TASTES nice.)

Words belonging to one of the following groups tend to be uncountable:
1. Сollective (the elements it comprises of are normally countable): luggage (but "suitcases"), furniture (but "chairs, tables"), machinery (but "machines"), food, cash, underwear, mail, equipment, garbage, litter, rubbish;
