As defined in wiki: https://en.wikipedia.org/wiki/Inflection

In linguistic morphology, inflection (or inflexion) is a process of word formation, in which a word is modified to express different grammatical categories such as tense, case, voice, aspect, person, number, gender, mood, animacy, and definiteness
