adjectivization

This term is a specialized linguistic technicality used primarily in morphology and syntax. It describes the specific structural change where a word's grammatical category is shifted to an adjective, often through the use of derivational suffixes like -ly, -ish, or -able. It is rarely encountered outside of academic papers, grammar textbooks, or professional linguistic analysis.

Because it describes a conceptual process rather than a physical object, the word is treated as an uncountable noun. It refers to the general phenomenon of conversion rather than individual instances of the act.
