Which part of speech uses the suffix -ize?

The suffix -ize is typically used to create verbs from nouns or adjectives. When added to a base word, it often transforms a concept into an action or process. For example, the noun "organ" can become the verb "organize," indicating the action of arranging or structuring something. This transformation highlights the ability of the -ize suffix to indicate the performance of an action or the state of becoming a certain way.

Other parts of speech do not commonly utilize the -ize suffix for their formation. Nouns, adjectives, and adverbs generally have different suffixes that correspond to their roles in language. Therefore, understanding that -ize functions specifically to form verbs clarifies why it is associated primarily with that part of speech.
