'amebian' originates from the Greek word 'amoibē,' meaning 'change,' referring to the changing shape of the organism.

'amoibē' transformed into the Latin word 'amoeba,' and eventually became the modern English word 'ameba' and its adjective form 'amebian.'

Initially, it meant 'changeable or mutable,' but over time it evolved into its current meaning of 'relating to or resembling an ameba.'
