'death-accepting' is a compound formed from 'death' and the participial adjective 'accepting'. 'death' originates from Old English 'dēað' meaning 'death', and 'accepting' derives from Latin through Old French ('accipere' -> 'accepter') where 'ac-'/'ad-' meant 'to, toward' and 'capere' meant 'to take'.

'death' comes from Old English 'dēað' (Proto-Germanic *dauthuz) and remained largely stable in meaning; 'accept' entered English via Old French 'accepter' from Latin 'accipere', later forming the participle 'accepting' that combines with nouns to make adjectival compounds such as 'death-accepting'.

Initially, 'death' and 'accept' had their separate original senses ('death' as the state of dying; 'accipere' as 'to receive/take'), but combined as a modern compound they specifically describe an attitude or stance of accepting mortality.
