'future-related' originates from English, specifically the words 'future' and 'related'. 'Future' comes from Latin 'futurus' (from 'esse' meaning 'to be') via Old French and Middle English; 'related' comes from Latin 'relatus', the past participle of 'referre' (re- + 'ferre' meaning 'to carry'), via Old French and Middle English.

'future' came into English via Old French 'futur' and Middle English 'futur(e)', while 'related' developed from Latin 'relatus' to Old French 'relater' and Middle English 'relaten'; the compound 'future-related' is a modern English formation combining these two elements to express a connection to the future.

Initially, the separate elements meant 'about to be' ('future') and 'brought back/connected' ('related'); over time they combined in modern usage to mean 'connected with what will happen' as in 'future-related'.
