- Causing distress or worry; upsetting or unsettling.
1898, Winston Churchill, chapter 8, in The Celebrity:
- I corralled the judge, and we started off across the fields, in no very mild state of fear of that gentleman's wife, whose vigilance was seldom relaxed. And thus we came by a circuitous route to Mohair, the judge occupied by his own guilty thoughts, and I by others not less disturbing.
