Ocean in a sentence as an adjective?

Answer 1

One way that ocean could be used as an adjective (a word that modifies a noun or pronoun), would be to change its form. If you make ocean possessive, it would be considered an adjective, as all possessive forms are adjectives.

For example:

The ocean's foam was thick and frothy.

In this example, the word ocean's modifies the noun foam. Because it modifies a noun, it is an adjective. Any word that modifies a noun or pronoun is an adjective.

You could use ocean as an adjective (a word that modifies a noun or pronoun) by alluding to some aspect of its qualities. For instance, the view of an ocean is far and wide as you can see. So, you could refer to an ocean of people were at the speech.

In the example you used, "the view of an ocean is far and wide as you can see," the word "ocean" functions as the object of a preposition. All objects are nouns or pronouns, so this would be incorrect. In that example, the word "ocean" functions as a noun.

Answer 2
