Which sentence uses capitalization correctly for a proper noun and a season?

• A. my friend visited Paris last summer.
• B. My friend visited Paris last Summer.
• C. My friend visited Paris Last summer.
• D. My friend visited Paris last summer.

Answer: (D)

Capitalization for proper nouns and seasons. A proper noun names a specific place, person, or thing, so Paris must be written with a capital P. Seasons, like summer, are common nouns and stay lowercase unless they are at the very start of a sentence or part of a title. In the sentence that reads “My friend visited Paris last summer,” the first word starts the sentence, so it is capitalized; Paris is capitalized as the city; and summer remains lowercase. The other options mix up these rules by capitalizing the season in the middle of the sentence or leaving the first word in lowercase, which is not correct. This sentence follows the standard rules clearly.
