'imperfectly-shaped' originates from the combination of 'imperfectly' and 'shaped', where 'imperfectly' is derived from Latin 'imperfectus', meaning 'not complete', and 'shaped' from Old English 'sceapian', meaning 'to form'.

'imperfectly-shaped' evolved from the Middle English 'imperfect' and 'shapen', eventually becoming the modern English term 'imperfectly-shaped'.

Initially, it meant 'not completely formed', and over time it evolved into its current meaning of 'having a form or shape that is not perfect'.
