What is the adjectival form of Plato? "Platonistic"? For example, in the following sentence:

He made the Platonistic statement that there are truths, but there is also the Truth.

Or is it incorrect to turn a proper noun into an adjective?

Platonic -proper adjective

  • of, relating to, or characteristic of Plato or his doctrines.

    • the Platonic philosophy of ideal forms.

(This word platonic refers to the writings of Plato, an ancient Greek philosopher who wrote on the interesting subject of love- vocabulary.com)

  • If Shakespeare is the proper noun, Shakespearian is the proper adjective.

Edit: In English orthography, most proper nouns are capitalized, while most common nouns are not. English adjectives that derive from proper nouns are usually capitalized. These two things, taken together, have led to the creation of the lay terms "proper adjective" and "common adjective" with meanings analogous to the lay meanings of "proper noun" and "common noun". Proper adjectives are just capitalized adjectives. (wiki)

    I think I see "platonic" uncapitalized when it means a non-sexual relationship with someone, but "Platonic", capitalized, when it refers to a philosophy of mathematics followed by Platonists, holding that mathematical objects exist in the world independently of whether they have yet been discovered by mathematicians. – Greg Lee Jun 12 '15 at 16:01
