The Spanish word 'mole' actually has three distinct origins and meanings. As an adjective meaning 'soft', it comes from the Latin word 'mollis' meaning 'soft, flexible'. When used to mean 'large mass', it derives from the Latin word 'moles' meaning 'mass, bulk'. However, its most famous usage in Mexican cuisine, referring to a type of sauce, comes from the Nahuatl (Aztec) word 'mulli' meaning 'sauce'.

This is an interesting case where three completely different etymological paths led to the same spelling in modern Spanish, though with distinct meanings. The Mexican sauce meaning is particularly notable as it represents an indigenous American influence on Spanish vocabulary, rather than the typical Latin origins.

Some related Spanish words that might help you remember these meanings include 'molido' (ground up, as in ingredients for mole sauce), 'molar' (to grind), and 'blando' (soft, sharing the Latin root 'mollis'). The mass-related meaning connects to words like 'demoler' (to demolish) and 'moler' (to grind down), which involve breaking down large masses.

English speakers might recognize connections to several familiar words. From the 'soft' meaning (Latin 'mollis'), we get words like 'mollify' (to soften or appease) and 'emollient' (something that softens). From the 'mass' meaning (Latin 'moles'), we get words like 'demolish' (to destroy a mass), 'molecule' (literally a small mass), and even 'mole' itself when referring to a breakwater or massive structure. The sauce meaning has entered English directly from Spanish as 'mole' in Mexican cuisine.
