The copular verb "be" is manifested in eight forms: "be", "is", "am", "are", "was", "were", "been", and "being" in English. These verbs precede nouns or adjectives in a sentence, which become predicate nouns and predicate adjectives similar to those that function with a linking verb. They can also be followed by an adverb of place, which is sometimes referred to as a predicate adverb. For example: "Her daughter "was" a writing tutor." "The singers "were" very nervous." "My house "is" down the street."
