Inflection (definition)
From Scottish Gaelic Grammar Wiki
An affix that when added to a word, changes its case, number or gender. In English the affix –s is an inflectional affix that changes the number of a noun to the plural. Latin, for example is an inflectional language, and the ending affixes indicate a word’s relation to the other words in a sentence. For example, given the Latin word bruma (winter), the –a ending indicates that the word is feminine, singular, and in the accusative case.
