'coverall' originates from English, specifically the combination of 'cover' and 'all', where 'cover' meant 'to protect or shield' and 'all' referred to 'everything or the whole'.

'coverall' was formed in English by combining 'cover' and 'all' to describe a garment that covers the entire body.

Initially, it meant 'a garment that covers everything', and this meaning has largely remained the same in modern usage.
