Born in vs. Born at

In English, prepositions such as "at" and "in" are used to convey different types of information about time and place. When referring to a person's birthplace, "born at" and "born in" are two common expressions used to convey information about the specific location of a person's birth.

"Born at" is used when referring to the exact location where a person was physically born, such as a hospital, a house, or a particular city or town. For example, "She was born at St. Joseph's Hospital in New York City." In this example, the speaker is indicating that the person was born at a specific hospital in New York City.

On the other hand, "born in" is used when referring to the general location or country where a person was born. For example, "He was born in Canada" or "She was born in Mexico City." In these examples, the speaker is indicating that the person was born in a particular country or city, without specifying a specific location within that city or country.

As an English teacher, I would advise learners to be mindful of the nuances of prepositions and how they can convey different types of information. When writing or speaking about a person's birthplace, it is important to consider the context and choose the appropriate preposition to accurately convey the information you wish to communicate.
