干 and 扰 both convey disturbance, and 素 names a substance, so an interfering substance.

Characters in this word

The simplified 干 stands for more than one traditional character. In most words (饼干, 干杯) it is 乾; in others (干, 干活儿) (干扰) it is 幹 or 干.

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 乾; 干 is its simplified writing.

Close in sound todayThe sound part was a clue two thousand years ago — it often still helps, but not always.

The traditional form 擾 combines 手 (hand) with 夒, a sound part; the simplified 扰 is a later shorthand, so its visible pieces are not the historical parts.
