CAPITALIZATION

"Capitalization is writing a word with its first letter as a majuscule (upper case letter) and the remaining letters in minuscules (lower case letters), in those writing systems which have a case distinction. The term is also used more broadly to refer to any aspect of using upper and lower case letters." (taken from http://en.wikipedia.org/wiki/Capitalization)
