C_Urala  +  442806 Thu, 15 Nov 07 07:39 AM I mean all dictionaries I have say it's uncountable. However, in scientific papers, it's common to discuss dependence of one parameter on another at different conditions. For example, over one catalyst, a reaction rate can decrease with temperature, whereas over another, it can increase with it. Is it ok to say that   there are two "dependences" of the reaction reate on temperature? Actually, I've met the plural of this noun, but in papers of foreign authors... Is the plural possible in this case? Or what should I write? Thank you in advance... C_Urala Joined on Thu, Nov 15 2007 Russia New Member 01 Plurals, Nouns

	Mister Micawber  +  442808 Thu, 15 Nov 07 07:55 AM Yes, I think in a specific context you could make 'dependence' countable-- at least, that is the case for many (most?) non-count nouns.  Most dictionaries do not note the opposite possibility for nouns that are primarily one or the other.
