Main verbs
Main verbs have meanings related to actions, events and states. Most verbs in
English are main verbs:

Several different types of volcano exist.
Linking verbs
Some main verbs are called linking verbs (or copular verbs). These verbs are
not followed by objects. Instead, they are followed by phrases which give extra
information about the subject (e.g. noun phrases, adjective phrases, adverb
phrases or prepositional phrases). Linking verbs include:
    appear             feel          look               seem            sound
    be                 get           remain             smell           taste
    become
