From Greek *ἰδέα* (idéa, "form, pattern"), related to *εἶδος* (eîdos, "form, shape"). Initially referred to a Platonic form, then broadened to any mental concept.
The concept of 'idea' can be traced back to ancient Greek philosophy, where it was used by Plato to describe perfect and unchanging forms. The meaning has evolved over time.
