Many English learners make mistakes with uncountable nouns — and these mistakes are common even at advanced levels. Words like information, advice, feedback, and knowledge cannot be made plural in English. We do not say 'informations' or 'advices'. We say 'some information' or 'a piece of advice'. News is also uncountable — it always takes a singular verb: 'The news is good!' not 'The news are good.' Equipment and furniture are uncountable too: 'The equipment is ready.' If you need to count an uncountable noun, use 'a piece of': two pieces of advice, three pieces of equipment. Learning these prevents very common professional errors.

💡 Did you know? English has around 100 common uncountable nouns that regularly cause errors even for advanced learners. Interestingly, some words are countable in some contexts and uncountable in others — two coffees please (cups of coffee) versus I do not drink coffee (the substance).
