Etymology

PIE word *reh₁ís From real (adjective) + -ize (suffix denoting the making of what is indicated by the word it is attached to), possibly modelled after French réaliser, Middle French réaliser (“to make real; to convert (something) into assets or cash”), from real (“actual, real”) + -iser (suffix denoting the making of what is indicated by the word it is attached to). Real is derived from Old French reel, from Latin reālis (“actual, real”), from rēs (“deed; event; matter; thing”) (ultimately from Proto-Indo-European *reh₁ís (“goods; wealth”)) + -ālis (suffix forming adjectives of relationship).
