Here's why:
* Proper Nouns: These are names of specific people, places, or things. They are always capitalized. For example, John, London, or the Eiffel Tower.
* Common Nouns: These are general names for people, places, or things. They are not capitalized. For example, boy, city, or building.
"Maestra" is a common noun meaning "female teacher" in Spanish. It's used to refer to any female teacher in general.
To make "maestra" a proper noun, you would need to add a specific name, like:
* Maestra Maria (Maria, the teacher)
* Maestra Garcia (Garcia, the teacher)
