Answer:
Capitalization
Step-by-step explanation:
The term that refers to the placement of capital letters is capitalization. Certain words are written with their first letter as a capital letter (uppercase letter) and the remaining letters in lower case. For example, the first letter of the first word in a sentence is always capitalized. Proper nouns are also always capitalized (e.g. names, holidays, days of the week and months, streets, etc).
