Final answer:
The title "The Once and Future King" is capitalized correctly according to standard rules for capitalization in titles, which require capitalization of both the first and last words, as well as all significant words in between.
Step-by-step explanation:
Whether the title "The Once and Future King" is capitalized correctly can be understood by examining capitalization rules. When it comes to titles of works, the general rule in English capitalization is to capitalize the first letter of the first and last words of the title, as well as the first letter of all the main words in between. However, certain shorter words, such as articles ('a,' 'an,' 'the'), conjunctions ('and,' 'but,' 'or'), and prepositions ('in,' 'on,' 'over') of fewer than five letters, are usually not capitalized unless they are the first or last word of the title.
In the title "The Once and Future King," 'The' is correctly capitalized as it is the first word of the title. 'Once' and 'Future' are main words that convey significant meaning and therefore are correctly capitalized. 'And' is a conjunction and should also be capitalized within a title. 'King' is capitalized because it is the last word of the title. Given these rules, the title "The Once and Future King" is indeed capitalized correctly.
For any additional assistance with capitalization in titles of works, resources such as online guides or dictionaries like Merriam-Webster can be helpful references. These tools can clarify capitalization rules and ensure that titles are formatted grammatically correct in academic writings or literary discussions.
