Question #1aa66

Answer 1

The sentence "Van has come." is grammatically correct IF the noun "Van" is the name of a person.

Explanation:

A proper noun is not usually preceded by an article.

If the noun "van' is a common noun, a word for a type of vehicle, the noun should be preceded by the article "the" when the "van" is one that is expected, or preceded by the article "a" when the "van" is not one that is expected; for example:
-- "The van has come."
-- "A van has come."

Examples of the proper noun that may be preceded by an article:
--"The note is from a Van." (the speaker doesn't know who Van is)
-- "Oh, that's the Van at my job." (a person that the speaker knows)
