The state, relationship, or bond of being cousins; kinship through a common ancestor removed by at least two generations.
From 'cousin' + '-ship' (state of being or relationship), paralleling 'friendship' and 'kinship', and referring to the family bond and social status of cousin relationships.
'Cousinship' sounds formal and archaic, but it actually describes something important—the way cousin relationships carried legal and social weight in medieval inheritance and family hierarchies.
