Covered with bushes, shrubs, and small trees; wooded, thickly vegetated, or resembling a forest or woodland.
From 'bosk' (small wood) plus the adjective-forming suffix '-y,' which transforms nouns into adjectives meaning 'full of' or 'characterized by.' Entered English through Middle English.
Modern poets and fantasy writers still use 'bosky' because it sounds ethereal and mysterious in a way that 'wooded' or 'bushy' simply cannot—one word evokes an entire enchanted mood.
