Icadia  +  958915 Sun, 01 Nov 09 01:42 PM I know some nouns can be either countable or uncountable. when I look for something in my dictionaries, I can notice a subtle difference between nouns. Some nouns have their definitions starting with "[U, C]" In OALD7, and other nouns have their definitions starting with "[C, U]" What's the exact difference between them? I think Nouns starting with "[U, C]" in their definitions mean that the noun is used as an uncountable noun for the most part, but sometimes, It can also be used as a countable noun , and "[C, U]" is the reverse. am I thinking right? I need your advice. Icadia Joined on Wed, Dec 17 2008 New Member 45 Difference Between, Nouns, Uncountable Nouns, Countable Nouns, Usages

If you need help in understanding the difference between countable and uncountable nouns, you might try typing "countable" in the search box above on the right (not the Google one). The subject comes up every day, and you should find hundreds of threads on it. (actually, thousands) I just worked on a post about "vacancy," which can be C  or U. How many vacancies do you have in your apartment building?  C Since all the forclosures, housing vacancy is a big problem.  U Avangi Joined on Mon, Nov 19 2007 Veteran Member 8,172 ". . . le plaisir delicieux et toujours nouveau d'une occupation inutile." - Henri de Regnier Difference Between, Nouns, Uncountable Nouns, Usages
