The Spanish word 'verificación' (verification) comes from the Latin word 'verificare', which was formed by combining two Latin elements: 'verus' meaning 'true' and 'facere' meaning 'to make'. So literally, it meant 'to make true' or 'to prove true'. The Latin 'verificare' evolved into Spanish 'verificar', and then the suffix '-ción' was added to create the noun form 'verificación', indicating the action or process of verifying something.

Some related and simpler Spanish words include 'verdad' (truth) and 'verdadero' (true), which come from the same Latin root 'verus'. The verb form 'verificar' is also more commonly encountered and might be easier to learn first. Another helpful connection is recognizing that many Spanish action nouns end in '-ción' (from Latin '-tio'), like 'comunicación', 'educación', and 'información'.

English speakers can easily connect 'verificación' to the English word 'verification', as they share the same Latin origin. Other related English words include 'verify', 'verity' (truth), 'veritable' (genuine, true), and even 'very' (which originally meant 'truly'). The 'veri-' beginning in these words all comes from Latin 'verus' (true). The '-fication' ending in English (as in 'verification', 'qualification', 'modification') corresponds to Spanish '-ficación' and comes from Latin 'facere' (to make).
