'amplexus' originates from Latin, specifically the word 'amplecti,' where 'am-' meant 'around' and 'plecti' meant 'to embrace.'

'amplecti' transformed into the Latin word 'amplexus,' and eventually became the modern English word 'amplexus.'

Initially, it meant 'to embrace or clasp,' but over time it evolved into its current meaning of 'a mating position in amphibians.'
