Generally:
* As an adjective: "Latino" is generally not capitalized when used as an adjective to describe something or someone. For example: "Latino culture," "Latino community."
* As a noun: "Latino" can be capitalized when used as a noun to refer to a person or a group of people. For example: "Latinos in the United States," "A Latino student."
Specific Style Guides:
* AP Style: The Associated Press style guide prefers lowercase "latino" for both adjective and noun uses.
* MLA Style: The Modern Language Association style guide also prefers lowercase "latino" unless it is part of a proper noun (e.g., "Latin America").
* Chicago Manual of Style: The Chicago Manual of Style generally follows the same lowercase usage as AP and MLA, but it allows for capitalization of "Latino" when used as a noun if the person or group prefers it.
Considerations:
* Preference: Some individuals and groups may prefer "Latino" to be capitalized, even when used as an adjective. It's always a good idea to be respectful of their preference.
* Clarity: If you're unsure, using lowercase "latino" is generally the safer choice to avoid potential misunderstandings.
In Conclusion:
While there's no definitive rule, it's generally recommended to use lowercase "latino" unless you're following a style guide that specifically calls for capitalization or unless the person or group you are referring to prefers it capitalized.
