The Spanish word 'ajado' meaning 'worn out' or 'withered' has an interesting connection to garlic! It comes from the Spanish word 'ajo' (garlic) combined with the past participle suffix '-ado'. The word 'ajo' itself derives from the Latin word 'alium' meaning 'garlic'. The connection between garlic and being worn out likely comes from the wrinkled, aged appearance of dried garlic cloves, which metaphorically extended to describe anything that looks weathered or worn out.

The most obvious related Spanish word is 'ajo' meaning 'garlic', which is much more common and simpler than 'ajado'. While 'ajo' retained its literal meaning referring to the pungent bulb vegetable, 'ajado' took on a metaphorical meaning based on the appearance of aged garlic.

While English 'garlic' is not etymologically related (it comes from Germanic roots), English borrowed the scientific name 'allium' directly from Latin to refer to the genus of plants that includes garlic, onions, and related species. This comes from the same Latin root 'alium' that gave Spanish 'ajo' and ultimately 'ajado'.
