Etymology
Origin of troublesome
Explanation
If something is troublesome, it annoys you or gives you difficulty. Your troublesome old car, for example, might be unreliable and have a history of breaking down at the most inconvenient moments. 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."
