Is the sellers a verb

Answer 1

Since you have put the definite article in front of the word 'patient', and it is not followed by another word, it can only be a noun:

'Who took the medicine?' 'The patient.'

Preceded by the article and followed by a noun, it would be an adjective:

'The patient dog was waiting for its owner outside the shop.'

The word on its own could be a noun or an adjective. But it could never be (except in Shakespeare) a verb!

Answer 2

No. A river is a place, therefore it is a noun.

A verb is a word that describes an action (run, walk, etc), a state of being (exist, stand, etc) or occurrence (happen, become, etc).

A noun is a word that is used to describe a person (man, lady, teacher, etc), place (home, city, beach, etc) or thing (car, banana, book, etc).

Answer 3

Yes 'is' is considered a verb, but 'is' is because 'he is' makes sense.

Answer 4

Yes it is because you can't be theing so it is not an action and it connects something so it is a linking verb.

Answer 5

Neither "in" nor "the" is generally considered to be a verb.

Answer 6

no. "the" is not a verb of any kind. It is the English definite article, which is a special type of adjective.
