'cohere' originates from Latin, specifically the word 'cohaerēre,' where 'co-' meant 'together' and 'haerēre' meant 'to stick.'

'cohaerēre' transformed into the French word 'cohérer,' and eventually became the modern English word 'cohere' through Middle English.

Initially, it meant 'to stick together,' and this meaning has largely remained the same in modern usage.
