'home-averse' is a modern English compound of 'home' + 'averse'. 'home' originates from Old English 'hām', meaning 'dwelling, estate', and 'averse' ultimately comes from Latin 'aversus' (past participle of 'avertere') via Old French/Middle English, where it meant 'turned away'.

'averse' changed from Latin 'aversus' → Old French 'avers' → Middle English 'avers(e)', and was used in Modern English as 'averse' meaning 'having a strong dislike'; combined with the Modern English noun 'home' (from Old English 'hām') to form the compound 'home-averse'.

Initially, 'aversus' meant 'turned away' in Latin; over time 'averse' came to mean 'having a strong dislike or opposition', and the compound 'home-averse' now specifically denotes 'having an aversion to being at home'.
