長官 vs 軽快

Q: What's the difference between 長官 and 軽快?

長官 (ちょうかん) means "chief, (government) secretary" and 軽快 (けいかい) means "rhythmical (e.g. melody); casual (e.g. dress); light; nimble". Both words are formal 2-kanji compounds often used in news. A 'chief' (長官) and a 'casual/light' (軽快) movement might be confused in listening due to their similar rhythmic 'Chō-kan' vs 'Kei-kai' patterns.
