Why is capitalization important?

Capitalization plays a crucial role in written communication, primarily because it helps to distinguish specific words that hold greater significance within the context of a sentence. For instance, capitalizing proper nouns such as names, titles, or locations indicates their importance and allows readers to identify them easily. Additionally, capitalization can indicate a change in meaning. For example, the difference between "polish" (meaning to make shiny) and "Polish" (referring to something from Poland) relies on capitalization to convey the distinct meanings clearly.

This answer highlights how capitalization is essential for clarity and understanding in written language, enabling readers to navigate texts more effectively. While the other options may address formatting or emotional emphasis, they do not encapsulate the primary function of capitalization in conveying meaning as effectively as this one does.
