The world, sphere, or domain of governesses; the collective status or condition of being a governess.
From 'governess' plus '-dom', a suffix meaning realm or domain (from Old English 'dom', meaning judgment or domain, as in 'kingdom' or 'wisdom').
The '-dom' suffix is a relic of Old English that we use to create abstract domains—'kingdom', 'wisdom', 'martyrdom'—and 'governessdom' is a literary way to describe the social world governesses inhabited!
