fish...deer...etc. uncountable nouns I'm sorry for asking some stupid questions sometimes, but what embarrasses me the most is that I usually write very grammatically complicated sentences, yet I make silly mistakes. When I speak about fish or deer , what pronouns should I use to refer to ( it / them )? If they are both used, which one is academical? And if there is one fish, can I say ( a fish )? Thanks in advance.
