nominalizacja

Also known as nominalization, substantivisation, substantivization

In linguistics, nominalization or nominalisation, also known as nouning, is the use of a word that is not a noun (e.g., a verb, an adjective or an adverb) as a noun, or as the head of a noun phrase. This change in functional category can occur through morphological transformation, but it does not always. Nominalization can refer, for instance, to the of producing a noun from another part of speech by adding a derivational affix (e.g., the noun "legalization" from the verb "legalize"), but it can also refer to the complex noun that is formed as a result.
