'aldimine' originates from the combination of 'aldehyde' and 'imine', where 'aldehyde' refers to a type of organic compound and 'imine' refers to a compound containing a carbon-nitrogen double bond.

The term 'aldimine' was formed by combining the words 'aldehyde' and 'imine' to describe a specific type of imine derived from aldehydes.

Initially, it meant a compound derived from aldehydes and imines, and this meaning has remained consistent in modern usage.
