The Spanish word 'peluca' (meaning 'wig') comes from two main sources that blended together: the French word 'perruque' (meaning 'wig') and the Spanish word 'pelo' (meaning 'hair'). The French influence provided the core meaning of 'wig', while the Spanish word 'pelo' influenced its form, making it more familiar to Spanish speakers by connecting it to the concept of hair.

A simpler and very common Spanish word related to 'peluca' is 'pelo' (meaning 'hair'). This connection makes perfect sense since a wig is essentially artificial hair. The relationship between these words helps Spanish learners remember that 'peluca' refers to a wig, as it's literally a thing made of 'pelo' (hair).

While English 'peruke' (an archaic word for wig) is related to 'peluca' through the French 'perruque', it's not commonly used in modern English. However, English speakers might recognize the connection between 'peluca' and words like 'peruke' and 'periwig' (another old-fashioned term for wig), though these words are now mainly found in historical contexts.
