The state, position, or status of being a beneficiary; the relationship or role of receiving benefit or inheritance.
From 'beneficiary' (Latin 'beneficiarius,' one who receives a benefit) combined with the suffix '-ship' (Old English 'scipe,' denoting status or condition, as in 'friendship' or 'membership').
The '-ship' suffix is reserved for important roles and relationships—'friendship,' 'kinship,' 'leadership'—so 'beneficiaryship' sounds formal and legal, the kind of thing you'd find in a will or trust document.
