In abbreviation usage, what is the correct formatting for abbreviations that include capital letters?

The correct formatting for abbreviations containing capital letters is that a space should be inserted between capital letters and other letters. This helps to enhance readability and clarity, particularly in instances where abbreviations are used alongside regular text. For example, when combining an abbreviation like “U.S.” with a following word, such as “law”, it is clearer to write “U.S. law” instead of “USlaw”, as the latter can cause confusion by blending the abbreviation with the following text.

In this context, it becomes evident that inserting spaces is important to distinguish between the abbreviation and the rest of the sentence. This convention is widely accepted in legal writing, where clarity is key.

Other formatting choices, such as bolding all capital letters or italicizing them, are not standard practices for abbreviation formatting and can create unnecessary distractions. Additionally, not leaving spaces between letters would make the text less readable and could potentially obscure the meaning of the abbreviation. Thus, the choice advocating for inserting spaces maintains both clarity and readability in written communication.
