the.com/consort

means To keep company with someone, especially in a way that raises eyebrows — or, as a noun, the spouse of a reigning monarch who shares the bed but not the throne.

from From Latin consors, 'one who shares a common lot or fate' — con- 'together' plus sors 'lot, share, destiny' (the same sors that gives us 'sort' and sits behind 'fortune'). A consort was originally simply a partner or companion in fate; the royal sense narrowed it to the partner who shares the monarch's bed and table but, pointedly, not the sors of ruling itself.
