Etymology
The word 'humanoid' is a modern English formation, directly combining the root 'human' with the suffix '-oid'. The root 'human' traces back to Latin humanus, meaning "of man, human," which itself is related to homo (man). The suffix '-oid' originates from the Greek -oeidēs, derived from eidos meaning "form, shape." This suffix was adopted into Latin as -oides and entered English to denote resemblance. Therefore, the literal construction "human-like form" perfectly captures the modern meaning of something—whether biological, robotic, or fictional—that resembles a human being in appearance or characteristics.
