To figure out if a noun is countable/ uncountable Hello, I have a question about a good way for English learners to check in an English dictionary if a word is countable or not. Usually, I depend on online dictionaries like Merriam-Webster and Oxford dictionaries. For instance, I checked the word "notice" to see if the noun form is countable or not. http://www.merriam-webster.com/dictionary/notice http://www.oxforddictionaries.com/definition/english/notice There are definitions of the word in noun and verb forms which are quite useful. However, as a English learner, I would like to know, at first, if the word is countable or uncountable since I still have difficulty to understand which vocabulary is countable or not. The fact that some words have different meanings depending on singular or plural forms is always scaring me. In the Ox-dictionary, there is a mention of "mass noun." Could it be a sign to see the word is uncountable? Thank you very much for your time and help in advance.
