Is the word sailed an adjective?

No, "sailed" is not an adjective. It is the past tense of the verb "sail".

Here's why:

* Adjectives describe nouns. For example, "The sailed ship" doesn't make sense because "sailed" doesn't describe the ship.

* Verbs show action or state of being. In the sentence "The ship has sailed," "sailed" shows an action that the ship has performed.
