The Spanish word 'ventura' meaning 'fortune' or 'luck' comes from the Latin word 'ventura', which meant 'things to come'. The Latin 'ventura' was formed by combining two parts: the verb 'venire' meaning 'to come' and the suffix '-ura' which indicated the result of an action. So literally, 'ventura' referred to the things that would come in the future, and this meaning eventually evolved to refer to one's fortune or luck in Spanish.

Some common Spanish words related to 'ventura' include 'venir' (to come), 'venidero' (upcoming, future), and 'aventura' (adventure). All these words share the same Latin root 'venire' (to come). While 'venir' directly inherited the meaning of 'coming', 'ventura' developed to mean the fortune that comes to someone, and 'aventura' evolved to mean an exciting experience that comes one's way.

English speakers might recognize the connection to words like 'venture', 'adventure', and 'avenue' (originally meaning 'approach'). These words also trace back to Latin 'venire' (to come). A 'venture' is something that comes as an undertaking or risk, while an 'adventure' is an exciting or dangerous experience that comes to someone. The connection between movement/coming and fortune/risk remains visible in both Spanish and English words from this family.
