Nominalization is when a word or a group of words are changed into a noun. This can be achieved by adding a suffix. Nominalizations are commonly derived from verbs, but they can be derived from other parts of speech, such as adjectives. An example of a verbal nominalization is the verb imply by turning it into the noun implication.

Deverbalization and substantivization is part of a two stage phonological process that generates a partial or total adapatation of a verb in order to name a higher-order entity. The role of conversion and affixation also take place during this process. Deverbalization tends to take the same set of complements as the verb it transforms.

The words stress rules are important for understanding language.
