Use the adjective troublesome to describe things — or people — that are worrisome or inconvenient. A troublesome stomach virus will keep you home from work, and a troublesome teenager is a constant source of anxiety and frustration for his parents. The word troublesome adds the suffix some, "tending to or causing," to trouble, which has a Latin Latin root, turbidare, "make trouble or make turbid." Turbid, by the way, means "muddy or full of confusion."
