'normal-shaped' originates from the English word 'normal' combined with 'shaped', where 'normal' meant 'conforming to a standard' and 'shaped' referred to the form or outline of something.

'normal' changed from the Latin word 'normalis' and 'shaped' from the Old English 'sceapian', eventually becoming the modern English word 'normal-shaped'.

Initially, 'normal' meant 'conforming to a standard', and 'shaped' referred to the form of something. This meaning has largely remained the same in modern usage.
