linking verb

Ah, I see. Please spell these things out! :) No, it is a transitive verb that has a direct object. "She has a nice disposition." A linking verb is intransitive with no direct object. "She is nice."

uh? Don't understand.

Ah, I see. Please spell these things out! :) No, it is a transitive verb that has a direct object. "She has a nice disposition." A linking verb is intransitive with no direct object. "She is nice." "is" is a linking verb, but "has" must have a direct object.

A linking verb has no direct object. "have" or "has" must have a direct object. You have something! A car, an iPhone...SOMETHING. So it is not a linking verb.

Yes, it is a verb, but not a LINKING verb. A linking verb has no direct object. Another example: "The eagle flew over the mountain." "flew" has no direct object, so is a linking verb. "over the mountain" is an adverb phrase, not a direct object. In this case, "flew" is a linking verb. "Have" must have a direct object, as I said above.

is there a action in the sentence?

a large number of the world's people have never seen an albino python.

Reed, could you please take a look at my question? Thank you!! :)

"have seen" is an action verb. ("never" is an adverb here). Seeing is action. It is a transitive verb in that "to see" requires a direct object. You have to see SOMETHING. An intransitive verb has no direct object. "Albino pythons exist." No direct object. Linking verbs are intransitive verbs (but not all intransitive verbs are "linking" verbs. In this case, "Albino pythons exist," there is no link to anything. "She is a nice person" uses the verb as a link to a description.
