sinecure: [17] Sinecure means literally ‘without cure’. It comes from the Latin phrase beneficium sine cūrā ‘benefice without cure’, that is to say an ecclesiastical office that does not involve the cure of souls (looking after people’s spiritual welfare), the usual duty of a priest. Hence it came to be applied to any appointment that involves payment for no work.
