A very large or highly successful educational institution.
The new superschool in the city has state-of-the-art facilities and a diverse curriculum.
Superschool is formed from "super-" (meaning above or beyond) and "school" (from Old Greek "scholē", meaning leisure or a place of learning). The word refers to an educational institution that is considered to be above or beyond the standard school in terms of quality or offerings.
Think of 'super-' meaning above or beyond, and 'school' as a place of learning. This helps you remember that a 'superschool' is an exceptional or advanced educational institution.
