'amioidei' originates from Greek, specifically the word 'amias,' where 'ami-' referred to a type of fish and '-oidei' is a suffix used in taxonomy to denote a group or family.

'amias' transformed into the Latin term 'amioidei,' and eventually became the modern scientific classification 'amioidei' in English.

Initially, it referred to a specific type of fish, but over time it evolved into its current meaning of a taxonomic group of fish.
