Etymology

Origin of trouble

First recorded in 1175–1225; (for the verb) Middle English troublen, from Old French troubler, from Vulgar Latin turbulāre (unrecorded), derivative of turbulus (unrecorded) “turbid,” back formation from Latin turbulentus “restless, unruly”; noun derivative of the verb; see turbulent

Explanation

Trouble is anything that causes difficulty, worry, and inconvenience, or that prevents you from doing something. If you have trouble getting along with a classmate, it is hard to be friendly with him or her. Whether you have trouble finding your shoes, you're in trouble with your teacher, or you go to a lot of trouble buying the kind of tea your sister likes, you face an annoying — and possibly distressing — difficulty. When you use trouble as a verb, it tells who or what is making life hard for you, like a headache that troubles you or childhood memories of encounters with scary clowns that probably trouble you even more deeply.
