'common-shaped' originates from the combination of 'common' and 'shaped', where 'common' means 'usual' and 'shaped' refers to the form or outline of something.

The term 'common-shaped' evolved from the Middle English 'commune' and 'shapen', eventually becoming the modern English term 'common-shaped'.

Initially, it meant 'having a usual form', and this meaning has largely remained the same in modern usage.
