Etymology
the word eidetic is a modern scientific term built directly from ancient greek components. it derives from the greek word eidos, meaning "form," "shape," or "that which is seen," which itself traces back to the proto-indo-European root weid-, meaning "to see." this root is the prolific ancestor of many sight-related words across languages, including latin videre (to see) and english wit. the suffix -etic, borrowed from greek -etikos, is used to form adjectives meaning "pertaining to" or "characterized by." thus, the literal construction "pertaining to an image" perfectly captures the modern psychological meaning of vividly recalling visual forms, maintaining a clear semantic link from the ancient concept of sight to the specific modern cognitive phenomenon.
