Sentence case refers to the capitalization style where the first letter of a sentence is capitalized, while the rest of the sentence is written in lowercase, except for proper nouns and certain other specific words that require capitalization.
For example:
In sentence case, only the first letter of the first word in a sentence is capitalized, regardless of the type of word it is (e.g., noun, verb, adjective). All other words in the sentence, except for proper nouns (e.g., names of people, places, or organizations) and specific words that are always capitalized (e.g., "I" as a pronoun, or "Jane" as a name in the example above), are written in lowercase.
Sentence case is commonly used in regular text and writing, such as in articles, essays, emails, and general communication. It is the default capitalization style in most cases when writing in English, unless a different capitalization style is specified or required (e.g., title case, uppercase, etc.).
