The state or practice of ruling jointly or together, a rare variant of 'coregency.'
From 'co-' (together) + 'regence' (from Latin 'regere' to rule, + '-ence' noun suffix). This is an archaic or literary variant.
Words ending in '-ence' and '-ency' (like 'presence/presency' or 'agency/agence') often show British versus American spelling preferences, but they also reveal how language changes—older forms get abandoned when simpler versions work just as well.
