Final answer:
The incorrectly capitalized word in the sentence is 'christmas', which should be 'Christmas' as it is a proper noun referring to a holiday.
Step-by-step explanation:
The word in the sentence that is incorrectly capitalized is 'christmas'. In English, the names of holidays are proper nouns and should always be capitalized. Therefore, the correct way to write the sentence is: 'For Christmas, we are planning to spend a few days in New York.'
Capitalization is the use of capital letters (uppercase letters) in writing. It's used to give importance to certain words, signal the beginning of sentences, highlight proper nouns (like names of people, places, or things), and emphasize specific words or titles.
In English, some common rules for capitalization include:
Beginning of Sentences: The first letter of the first word in a sentence is capitalized.
Proper Nouns: Names of specific people ("John"), places ("Paris"), organizations ("United Nations"), and days/months ("Monday," "January") are capitalized.
Titles: The first and important words in titles of books, movies, articles, etc., are usually capitalized.
