means An educational program for young children, typically ages 3-5, that prepares them for kindergarten through structured play and early learning.

from Straightforward English compound: 'pre-' (from Latin prae, 'before') plus 'school' (from Greek skholē, which originally meant 'leisure' or 'spare time' — ancient Greeks saw learning as what you did when freed from labor). The word simply marks the stage that comes before formal schooling begins, a 20th-century coinage that grew alongside the modern idea that early childhood education deserves its own institution, not just a waiting room for 'real' school.
