In grammar, the different forms (inflections) taken by nouns, pronouns, and adjectives depending on their function in a sentence. English is a language with four inflections; most words have no more than two forms. For example, six pronouns have one form when they are the subject of the verb, and a different form when they are either objects of the verb or governed by a preposition. The six are: I/me, he/him, we/us, they/them, who/whom. In “I like cats”, I is the subject of the sentence. In “Cats hate me”, me is the object. Latin has 6 cases, and Hungarian more than 25.

In text processing, an indication of whether one or more alphabetic characters are capitalized (uppercase) or not (lowercase). A case-sensitive program or routine distinguishes between uppercase and lowercase letters and treats the word cat as totally distinct from either Cat or CAT. A case-sensitive program that also separates capitalized and lowercased words would list Arkansas before aardvark or antimony, even though its alphabetic position follows both lowercased words.
Upper and lower; The two possible forms taken by letters of the alphabet: capitals (upper case) and lower case. Capitals are used to begin proper nouns (John, Concorde, Dr Smith); the beginning of a sentence; the beginning of a sentence of direct speech (He said: “Come here!”); and the principal words in a title (Far from the Madding Crowd).
In the days when typesetting was done by hand, printers used to keep letters in a low case, near to hand; the less often used capitals were stored in a higher (upper) case.
