Did you know?
- The word claro is a linguistic rarity because it preserves the original Latin 'kl-' sound, which usually transforms into a 'll-' sound in Spanish words.
- The expression desde luego uses the word luego, which usually means 'later'. In this specific phrase, it refers to a logical sequence of events rather than a clock time.
- In many Spanish-speaking regions, saying claro que sí with a rising intonation can actually signal that you are being sarcastic rather than enthusiastic.
