1. The action of verbalizing or the fact of being verbalized.
2. A verbal expression or statement.
3. In psychiatry, the state of being verbose or diffuse, commonly encountered in an extreme degree in patients with the manic form of manic-depressive psychosis.

In a more general sense, verbalization refers to the expression in words of thoughts, wishes, phantasies, or other psychic material that had previously been on a nonverbal level because of suppression or repression. “Verbalize” is often used in a pseudoerudite way when “talk about” is meant.
