How about having 'naam' as the literal translation of 'Form'.? It, perhaps is identical with
Dravya and Guna .

May be it will be worthwhile recalling the sloka from the Upanishad-

Asti Bhati Priyam Naam Rupam Cetashhya Pancha kam.

Addya Trayam Brahma Rupam Jagat Rupam Ttato Dwayam.

ALAKENDU DAS.
