shifty-eyed

the compound adjective 'shifty-eyed' is a relatively modern formation in english, combining two native elements. the first part, 'shifty', derives from the verb 'shift', which entered middle english from old english 'sciftan', meaning to arrange or divide, and later evolved to imply moving or changing position, often with connotations of evasion or deceit. the second part, 'eyed', is the adjectival form of 'eye', from old english 'ēage', of germanic origin. when combined, the term literally describes someone characterized by having eyes that shift or move evasively, directly linking the physical behavior of avoiding direct gaze to the abstract judgment of being untrustworthy or sly. this metaphorical extension from a literal visual cue to a character assessment is a common pattern in english descriptive terms.

Structure: shifty + eyed shifty (from english 'shift', meaning to change or move evasively, + suffix '-y', forming an adjective meaning characterized by shifting) + eyed (from english 'eye', meaning the organ of sight, + suffix '-ed', forming an adjective meaning having eyes of a specified kind).
