The Spanish word 'celar' is interesting because it actually has three distinct meanings and etymological paths. The first meaning, 'to be jealous,' comes from the Greek word 'zelos' (ζῆλος) meaning 'zeal' or 'jealousy,' which entered Latin as 'zelari' before becoming Spanish 'celar.' The second meaning, 'to conceal,' derives from the Latin word 'celare' meaning 'to hide or conceal.' The third meaning, 'to engrave,' comes from the Latin 'caelare' meaning 'to engrave.' This is a fascinating case where three different Latin words with distinct meanings converged in Spanish to create a single word with multiple uses.

The Spanish word 'celo' (zeal, jealousy) is closely related to the first meaning of 'celar.' You might also encounter 'celoso/celosa' meaning 'jealous.' These words share the same Greek root 'zelos.' The word 'celada' meaning 'ambush' or 'trap' is related to the second meaning of 'celar' (to conceal), as an ambush involves hiding or concealment.

Several common English words are related to 'celar.' The English words 'zeal,' 'zealous,' and 'jealous' all come from the same Greek root 'zelos' that gave us the first meaning of 'celar.' The English word 'conceal' is a direct relative of the second meaning of 'celar,' both coming from Latin 'celare.' For the third meaning, the English word 'ceiling' (originally referring to carved or engraved panels) is distantly related, sharing the Latin root 'caelare' meaning 'to engrave.'
