In addition to the British use of English, this dictionary also shows American usage. The other key aspect of this dictionary, particularly important for the French who use definite articles for all nouns, is its specification of uncountable (mass) nouns versus countable (count) nouns. This dictionary also shows when uncountable (mass) nouns can be used in countable (count) sense. For example, what is the difference between "water" versus "waters", which one is to be used in which situation.
