'routine-based' originates from the word 'routine,' which comes from the French word 'routine,' meaning 'a regular course.' The suffix '-based' is used to indicate dependency or foundation.

'Routine' was borrowed from French in the 17th century, and the concept of 'routine-based' emerged as a compound adjective in modern English.

Initially, 'routine' referred to a regular course or procedure, and 'routine-based' has maintained this meaning, emphasizing dependency on such procedures.
