Hmm.. there are several things wrong with each of the scenarios you indicated but strangely enough, the quantity agreement of the subject/predicate isn't one of them.Originally Posted by bmo
English isn't like so many other languages where nouns have to agree with pronouns and adjectives in number and gender (most of the time).
"My favorite animal is dog"
You're just missing the article "the" that indicated dog is singular. "Is" doesn't have to agree with anything else in the sentence, and "dog" and "animal" certainly don't have to.
"My favorite animal is the dog"
"My favorite animals are dogs"
"Our favorite animal is the dog"
"Our favorite animals are dogs"
Are all correct and none of them *require* an agreement between the subject and the predicate in terms of quantity.
HOWEVER : if you decide to change the meaning of the sentence to reflect something else more abstract then it's totally ok to leave out the article.
For instance : "My favorite food is dog"
In that case you don't need an article. You aren't talking about one dog or many dogs, you're just talking about dog in general being your favorite thing to eat.
