Is grown a linking verb

Answer 1

Grown can be a linking verb. For example:

Your lawn has grown green with care. Grown is the linking verb because the object is another form of the subject.

You've grown a great lawn. This time grown is not a linking verb because the object is not another way to say the subject.

You sure have grown. Here, grown is not a linking verb because there is no object to link to the subject.
