I was trying to classify certain plural nouns in form but I couldn´t find the category of: Scissors, Jeans, shorts, etc. I understood that as they are plural in form, the verb would go on the plural because of the verb agreement with the noun. How about the rest of the rules for countable and uncountable nous? (E.g. Can I say I need 3 scissors..?? or 3 shorts?. I heard it quite often although i think that grammatically should be 3 pairs of.... ) Thanks for your help!
