'amphimorula' originates from Greek, specifically the word 'amphi-' meaning 'both' or 'around' and 'morula' meaning 'little mulberry', referring to the appearance of the cell cluster.

'amphi-' combined with 'morula' in scientific Latin to form 'amphimorula', used in embryology.

Initially, it referred to a 'little mulberry', but over time it evolved into its current meaning of a stage in embryonic development.
