Capitalization

use of a capital letter at the head of a word
(Redirected from Capital letter)

Capitalise (British spelling) or capitalize (North American spelling) means to make one or more letters upper case. The first letter of a sentence is capitalised in many languages, as are the first letters of proper nouns such as names of people and places. In German, however, all nouns are capitalized. It is the only language to do that.

The homonym capitalize is a different word, and means "to fully fund as an investment".
