'dependably' originates from the English word 'dependable', which is derived from the Latin word 'dependere', where 'de-' meant 'from' and 'pendere' meant 'to hang'.

'dependere' transformed into the Old French word 'dependre', and eventually became the modern English word 'depend' through Middle English.

Initially, it meant 'to hang from', but over time it evolved into its current meaning of 'to rely on'.
