saucer

The word "saucer" has a delightfully literal origin. It entered English in the 14th century from the Old French sauciere, meaning "sauce dish" or "condiment container". The French term itself derived from the Latin salsus, meaning "salted". The original English "saucer" was precisely that: a small dish for holding sauces or condiments. Over time, as dining customs evolved, its primary function shifted to holding a teacup, catching drips, much as it once held sauces. The modern abstract meaning of any shallow, disk-shaped object, most famously a "flying saucer", extends directly from this familiar domestic shape.

Structure: sauc (sauce) + er (agent/instrument suffix) - sauc: From Old French sauce, meaning "sauce, condiment". Its functional role is the core semantic root. - er: A Germanic/English agentive suffix, here indicating an object used for a specific purpose.
