'desorbate' originates from the Latin prefix 'de-' meaning 'from' or 'away' and the root 'sorbēre' meaning 'to suck in'.

'desorbate' evolved from the Latin word 'desorbere', which was used in scientific contexts to describe the process of removing a substance from a surface.

Initially, it meant 'to remove by suction', but over time it evolved into its current meaning of 'a substance that has been released from a surface'.
