The Spanish word 'cocainómano' (cocaine addict) is a compound word formed from two main parts: 'cocaína' (cocaine) and 'manía' (mania, obsession). The first element 'cocaína' comes from 'coca' plus the chemical suffix '-ina'. The word 'coca' itself can be traced back to the Quechua/Aimara word 'kuka', referring to the coca plant native to South America. The second element 'manía' derives from Latin 'mania', which in turn comes from Ancient Greek 'μανία' (manía) meaning 'madness' or 'frenzy'. The compound literally means 'one who has a mania/obsession for cocaine'.

Some simpler related Spanish words include 'coca' (the coca plant itself) and 'manía' (obsession, craze). These are both more common words that Spanish learners might encounter. 'Manía' is often used in everyday contexts to describe any kind of obsession or fixation, like in 'manía por los dulces' (obsession with sweets).

English speakers can recognize the connection to several familiar words. 'Cocaine' follows the same etymology as the Spanish 'cocaína', both coming from 'coca' plus a chemical suffix. The word 'mania' is directly related to Spanish 'manía', both preserving the meaning of an intense obsession or mental state from their shared Greek ancestor. We see this in English words like 'maniac' and in psychiatric terms like 'manic depression'.
