Late Middle English: from Old French pertourber, from Latin perturbare, from per- 'completely' + turbare 'disturb'.
trouble from Middle English:
Our word trouble comes, by way of Old French truble, from Latin turbidus ‘disturbed, turbid’, source of turbid (early 17th century), and related to disturb (Middle English), perturb (Late Middle English), and turbulent (mid 16th century). From the start, in the 13th century, it meant ‘difficulty or problems’. ‘Man is born unto trouble, as the sparks fly upward’ is from the biblical book of Job who was a virtuous man that God tested by sending him many troubles. Most people now think of the Troubles in Northern Ireland as beginning in the early 1970s, but the same term applied to the unrest around the partition of Ireland in 1921, and in an 1880 glossary of words used in Antrim and Down the Troubles are defined as ‘the Irish rebellion of 1641’. The first troubleshooters had a very specific occupation. In the early years of the 20th century they mended faults on telegraph or telephone lines.
