What does ideal mean?
“Ideal” describes the best possible version of something or the highest standard it could reach. As an adjective, it may characterize an aim, circumstance, person, or example: an ideal home need not be luxurious, only well suited to its occupants and free from serious faults. As a noun, an “ideal” can be a model of perfection, as in the ideal of honest government, or a person regarded as embodying exceptional qualities. The word often carries an aspirational or slightly idealized quality, suggesting a standard that may be difficult to attain in practice. Consequently, “ideal” can be used approvingly of plans and opportunities, but it may also imply that a situation is being viewed from an unusually demanding perspective. In everyday English, it is formal enough for careful description but not restricted to technical or literary contexts. Its usefulness lies in connecting concrete choices with broader standards of excellence.

Where does ideal come from?
The word entered English in the early 17th century from Latin idealis, meaning “pertaining to an idea” or “existing as an idea.” Latin idealis was formed from idea, a borrowing of Greek idea, meaning “form,” “pattern,” or “notion.” The mathematical sense developed first, while the modern general sense of a perfect model or the best possible standard followed through later philosophical and figurative usage.
