'Lent-related' is a compound of 'Lent' and 'related'. 'Lent' originates from Old English, specifically the word 'lencten', where 'lencten' meant 'spring (lengthening of days)'. 'related' originates from Latin, specifically the word 'relatus' (from 'referre'), where 're-' meant 'back' and 'ferre' meant 'to carry'.

'Lent' changed from Old English 'lencten' to Middle English 'lente' and eventually became the modern English 'Lent'. 'related' came into English via Old French and Middle English forms from Latin 'relatus', evolving into the modern English 'related'.

Initially, 'Lent' meant 'spring/lengthening of days' and later became the church term for the 40-day fasting period; 'related' originally had senses from Latin of 'brought/borne' and evolved to mean 'connected'. Together, 'Lent-related' now means 'pertaining to Lent'.
