Etymology: "Sluggy" is about as plain as etymologies get: it is the English noun "slug" with the adjective-forming suffix "-y" attached. "Slug" in its ordinary sense of a slow-moving creature gives the word its core image, and the suffix turns that noun into a description of something behaving the way a slug does. The suffix does a lot of the work here. "-y" is one of the most productive endings in English, used to make adjectives meaning "full of," "having the quality of," or "resembling" the base noun, as in "milky" or "stony." Attaching it to "slug" produces a word that describes motion or a state as sluggish, heavy, and reluctant, the way a slug moves across the ground.
