'amplexus' originates from Latin, specifically the word 'amplexus', where 'am-' meant 'around' and 'plectere' meant 'to weave or twine'.

'amplexus' was directly borrowed from Latin into English, retaining its original form and meaning.

Initially, it meant 'an embrace or clasp', but over time it evolved into its current meaning of 'mating embrace of frogs and toads'.
