'anabathmos' originates from Greek, specifically the word 'ἀνάβαθμος', where 'ana-' meant 'up' and 'bathmos' meant 'step'.

'ἀνάβαθμος' changed from the Greek word 'anabathmos' and eventually became the modern English word 'anabathmos'.

Initially, it meant 'a step upwards', but over time it evolved into its current meaning of 'a step or degree in a process of ascent or progression'.
