An Ideal Language Type (also philosophical or a pr

is any constructed language that is built up out of first principles, such as a logical language. Such languages are in contrast to ordinary or spoken languages such as English, Italian, or Japanese (often called natural languages), which have within them a great deal of fuzziness, overlap, vagueness, ambiguity, multiple meanings, and indeterminacy of meaning for words and phrases, unclarity, inherent contradiction, and difference between intension and extension of terms—this is not necessarily a defect of natural languages, but may indeed constitute a strength of them.

An ideal language entails a stronger claim of absolute perfection or transcendent or even mystical truth rather than pragmatic principles. Philosophical languages were popular in Early Modern times, partly motivated by the goal of recovering what was thought to be the lost Adamic or Divine language.
