'symbiosis' originates from Greek, specifically the word 'symbiōsis,' where 'syn-' meant 'together' and 'bios' meant 'life.'

'symbiōsis' transformed into the Latin word 'symbiosis,' and eventually became the modern English word 'symbiosis' through New Latin.

Initially, it meant 'living together,' but over time it evolved into its current meaning of 'a mutually beneficial relationship between different organisms.'
