Capitalization

Capitalise (British spelling) or capitalize (North American spelling) means to make one or more characters upper case. The first letter of the 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 the different word, and means "to fully fund as an investment".
