啰 (luō) — used in 囉唣|啰唣

啰 is not used alone — it only appears as the first character of the colloquial verb 啰唣, meaning 'to bicker, squabble, make a fuss'.

Most characters — around four in five — are built this way: one part hints at the meaning, the other at the pronunciation.

This origin belongs to the traditional form 囉; 啰 is its simplified writing.

The traditional form 囉 has 口 (mouth) beside 羅, which supplies the sound; the simplified 啰 is a shorthand, so its right side is not 羅.
