Word encompassing all transformations of a word (conjugation, plurization, etc.)

Is there a singular word or phrase which encompasses all of the many types of transformations you may perform on a word, such as conjugation, pluralization, nominalization, adjectivization, etc.?

The best I've come up with so far is "transformations," but that is a very generic word. Having a word that is more precise would be great.

I would have thought I'd have been able to find the word by hunting around with those keywords, but I had no such luck.

Solution 1:

You are probably looking for declension:

In linguistics, declension is the changing of the form of a word, generally to express its syntactic function in the sentence, by way of some inflection.

Declensions may apply to nouns, pronouns, adjectives, adverbs, and articles to indicate number (e.g. singular, dual, plural), case (e.g. nominative case, accusative case, genitive case, dative case), gender (e.g. masculine, neuter, feminine), and a number of other grammatical categories.
