Which sentence demonstrates the capitalization rule for words with suffixes?

• A. This loud, loud noise is very Displeasing.
• B. This loud, loud noise is very disPLEASING.
• C. This loud, loud noise is very DISPLEASING.
• D. This loud, loud noise is very displeasing.

Answer: (D)

Capitalization in ordinary sentences follows position and names, not the presence of a suffix. The word with the suffix should stay lowercase unless it’s a proper noun or at the start of the sentence. In this sentence, the word "displeasing" isn’t a proper noun and doesn’t begin the sentence, so it remains lowercase. The sentence starts with "This," which is correctly capitalized because it begins the sentence. The other options raise the suffix with capitalization (Displeasing, disPLEASING, DISPLEASING), which isn’t required by standard rules. So the sentence that keeps the suffix lowercase shows the proper pattern: only the first word is capitalized and the rest of the sentence uses lowercase for regular words.
