Capital Letters Introduction

Capital letters, or uppercase letters, are not just for starting sentences. They have unique roles and historical significance in written language.

Originally, manuscripts in the Roman era used only uppercase letters. Lowercase letters evolved for efficient, faster handwriting.

Capital letters distinguish proper nouns, such as names and places, from other words, giving clarity and respect to the referenced entity.

Acronyms like NASA and abbreviations like Mr. use capital letters for emphasis and brevity, transforming long phrases into memorable and concise words.

Beyond grammar, capitalization can convey significance or urgency in a text, often seen in marketing or emotional expressions, like 'SALE' or 'WARNING!'

The word 'I' is the only pronoun consistently capitalized in English, a quirk unique among most languages.
