The word 'anatomiless' is formed in English by combining 'anatomy' with the suffix '-less', where 'anatomy' refers to the structure of living things and '-less' means 'without'.

'Anatomy' comes from the Greek word 'anatomē', meaning 'dissection', and '-less' is an Old English suffix meaning 'without'. The combination in modern English forms 'anatomiless'.

Initially, it would mean 'without anatomy' in a literal sense, and it retains this meaning in modern usage, often used figuratively for things lacking physical form.
