'sufficiently' originates from Latin, specifically the word 'sufficere,' where 'sub-' meant 'under' and 'facere' meant 'to make or do.' 'Related' comes from Latin 'relatus,' the past participle of 'referre,' meaning 'to bring back.'

'sufficiently' changed from the Old French word 'suffisant' and eventually became the modern English word 'sufficiently.' 'Related' evolved from the Middle English 'relaten,' which was derived from the Latin 'relatus.'

Initially, 'sufficiently' meant 'enough to meet the needs,' and 'related' meant 'brought back or connected.' Over time, 'sufficiently-related' evolved to mean 'adequately connected or relevant.'
