'consolidate' originates from Latin, specifically the word 'consolidare,' where 'con-' meant 'together' and 'solidare' meant 'to make solid.'

'consolidare' transformed into the French word 'consolider,' and eventually became the modern English word 'consolidate' through Middle English.

Initially, it meant 'to make solid or firm,' but over time it evolved into its current meanings of 'strengthen' and 'combine.'
