'ensconce' originates from Middle English, specifically the word 'sconce,' where 'en-' meant 'in' and 'sconce' referred to a small fort or shelter.

'sconce' transformed into the verb 'ensconce' in the late 16th century, eventually becoming the modern English word 'ensconce'.

Initially, it meant 'to shelter or hide,' but over time it evolved into its current meaning of 'to settle securely or comfortably'.
