Meaning
A school building, often with a clock on the front and sometimes a bell tower or flag. It stands for school, education, classes and student life.
Use it for the first day of term, exams, school runs and teacher chats: “Kids are back at 🏫 tomorrow, uniforms ironed”. It pairs with 📚, ✏️ and 🎒. Parents, teachers and students all use it, and it suits reunions and old-school memories too.
