Grammar Focus: Uncountable nouns - Articles

Uncountable nouns are mass nouns which we can’t count. Uncountable nouns include: a) solid substances or many kinds of food:coal, earth, flour, sugar, meet, cheese, rice, etc. b)liquids, gases:water, coffee, oil, petrol, wine, tea, air, smoke, oxygen, , steam, hydrogen. c)materials:silicon, iron, copper, silver, gold, brass, plastic , glass, paper, wool, cotton. d) languages: English, French, German, Japanese, Spanish, Italian, Danish, Dutch, etc. e) abstract nouns:knowledge, education, information, power conductivity, voltage, etc. f) words whose equivalents in other languages might be regarded as countable nouns:research, money, cash, advice, news,behavior, harm, weather accommodation, garbage, litter, rubbish, hardware, software, equipment, machinery, furniture, progress, luggage, baggage, jewellery, cutlery, poetry, lightning, leisure, luck, fun.

Uncountable nouns: - always take singular verbs. e.g. Gold is more expensive than silver. – don’t go with a/an/one/two when talking about things in general. e.g. Fresh air is healthy. Water is good for you. – can be used alone or with some/any/much/little/my/the. e.g. Don’t forget to buy (some) coffee.

We use singular verb forms and no articles with words which refer to school subjects or scientific studies: chemistry, economics, mathematics (maths), physics, politics, electronics, biology, programming, engineering, geometry, geophysics, etc.
