Etymology: "Platinoid" is a plain technical coinage: platinum with the suffix "-oid", from Greek "eidos", meaning "form" or "likeness", so the word means "resembling platinum." The suffix itself reached English through Latin "-oīdes" from Greek "-eidḗs," a pattern that produced many scientific adjectives such as "android" or "asteroid." The base word "platinum" entered English in the 18th century, borrowed from Spanish "platina," a diminutive of "plata," silver, which was the name given to the metal by Spanish colonists in South America who encountered it there and mistook it for a lesser form of silver. The Spanish word traces back to Vulgar Latin "plattus," from Ancient Greek "platús," meaning "broad" or "flat," so the root idea sits behind the silver-coloured metal itself.
