schoolfriend

The word "schoolfriend" refers to a friend from school. In the simplest sense, it means someone you were friends with while attending the same school. That friendship may have been close or fairly ordinary, but it was real enough that you think of the person as a friend, not just another student in the room. This is why the word is a little different from "classmate." A classmate is anyone in your class, but a schoolfriend is someone you actually talked to, spent time with, or shared part of daily school life with.

The word is often used when people talk about the past. Someone might say, "I ran into an old schoolfriend," meaning a person they were friends with years ago at school. In that kind of sentence, the word carries a natural feeling of memory and shared history. It can bring to mind lunch breaks, homework, games, school trips, and all the small things that filled those years. Still, the meaning itself is not as narrow or dramatic as "lifelong friend" or "best friend." A schoolfriend may have been very important, or simply one of the friends you had during that part of life.

It can also be used in the present for a friend you currently have at school, though in many contexts people use it when looking back. The main idea stays the same: the friendship is linked to school. So if you want to describe someone who was part of your social life during your school years, "schoolfriend" is a clear and natural word. It tells us not only that you knew the person at school, but that there was friendship there as well.
