'equally' originates from Middle English, specifically the word 'equale,' where 'equa-' meant 'equal.' 'Related' originates from Latin, specifically the word 'relatus,' where 're-' meant 'back' and 'latus' meant 'carried.'

'equale' transformed into the modern English word 'equal,' and 'relatus' transformed into the modern English word 'related' through Old French 'relater.'

Initially, 'equally' meant 'in equal parts,' and 'related' meant 'brought back or referred to,' but over time they evolved into their current meanings of 'in the same manner' and 'connected or associated,' respectively.
