* If you're talking about a noun describing a word or phrase, then "verbal" is NOT a verb. It's an adjective describing a noun. For example: "She gave a verbal warning."
* If you're talking about a verb in the grammatical sense, then "verbal" can be either transitive or intransitive depending on its usage.
* Intransitive: "He verbalized his concerns." (Meaning: He expressed his concerns in words).
* Transitive: "She verbalized the agreement." (Meaning: She put the agreement into words).
In short: "Verbal" is not a verb itself, but it can be used to describe a verb, which might be either transitive or intransitive.
