397. INFLECTION is the change which nouns, pronouns, and verbs undergo,
to indicate their relation in a sentence.
The inflection of a noun or pronoun is often called _Declension_, and
that of a verb, _Conjugation_.
(A.) INFLECTION OF THE NOUN.
398. The noun or pronoun is inflected by attaching case endings to the
stem.
The endings, which are called case endings for brevity, indicate number
as well as case, and serve also to distinguish gender words from neuters
in the nominative and accusative singular of some stems, and of all
plurals. These endings are nearly the same for stems of all kinds.
