The term 'life-related' is a compound word formed from 'life' and 'related'. 'Life' originates from Old English 'līf', meaning 'the condition that distinguishes animals and plants from inorganic matter'. 'Related' comes from Latin 'relatus', the past participle of 'referre', meaning 'to bring back'.

'Life' has remained largely unchanged from its Old English form 'līf'. 'Related' evolved from Latin 'relatus' through Old French 'relater', eventually becoming the modern English 'related'.

The term 'life-related' has consistently referred to matters concerning life or living organisms.
