The Spanish word 'temprano' (meaning 'early') comes from the Vulgar Latin word 'temporanus' meaning 'timely, early'. This evolved from Classical Latin 'temporaneus' meaning 'timely, seasonal', which was derived from the Latin root word 'tempus' meaning 'time'. The development from 'tempus' to 'temprano' shows how the concept of 'time' became more specifically associated with 'earliness' or 'being timely' in Spanish.

Several common Spanish words share this Latin root 'tempus', including: 'tiempo' (time), 'temporal' (temporary), and 'temporada' (season, period of time). While 'temprano' specifically came to mean 'early', these related words maintained meanings more directly connected to the original concept of time and temporal matters.

English speakers can connect 'temprano' to several familiar English words that come from the same Latin root 'tempus', such as 'temporal' (relating to time), 'temporary' (lasting for a limited time), and 'contemporary' (belonging to the same time). The word 'tempo' in music also comes from this root. While these English words kept meanings related to time in general, the Spanish 'temprano' specialized to mean specifically 'early'.
