'saucer-shaped' originates from the word 'saucer,' which comes from Old French 'saucier,' meaning 'sauce dish.' The suffix '-shaped' is used to denote the form or appearance of something.

'saucier' transformed into the Middle English word 'sawser,' and eventually became the modern English word 'saucer.'

Initially, 'saucer' referred to a small dish for sauces, but over time it evolved to describe any small, shallow dish, and 'saucer-shaped' came to describe objects resembling this form.
