Is the word became an adjective?

No, "became" is a verb. It describes an action or a state of being.

Here's why:

* Definition: "Became" is the past tense of the verb "become," meaning to come to be or to develop into something.

* Usage: We use "became" to describe a change or transformation. For example: "The caterpillar *became* a butterfly."

Adjectives, on the other hand, describe nouns. They tell us what kind, what color, or what quality something has.

Example: "The *beautiful* butterfly fluttered its wings."

* "Beautiful" is the adjective describing the butterfly.
