It is important to note that, in this linking verbs list, are verbs which can also be used as ‘action’ verbs. Remember that these are only linking verbs, when they link the subject to the subject complement.
Linking verbs differ from ‘helping verbs’ which help verbs to express tenses and always precede another verb e.g. was cooking, will be going, should have watched etc.
