Etymology
the word 'grooved' is built upon the noun 'groove', which entered english from middle dutch 'groove' or middle low german 'grōve', meaning a furrow or ditch. these germanic terms likely stem from a proto-germanic root related to digging or carving. the suffix '-ed' is a native english morpheme, one of the oldest and most productive in the language, used to form adjectives meaning 'having' or 'characterized by'. thus, 'grooved' literally means 'having a groove or grooves'. its modern informal sense, describing a smooth, efficient, or habitual pattern of action, is a metaphorical extension from the physical notion of a track or channel that guides motion.
Analysis
groove (from middle english grofe, grove, meaning 'mine shaft, pit', of germanic origin) + ed (old english suffix '-ed', '-od', '-ad', used to form adjectives from nouns or verbs, indicating possession of a quality).
