若 (ruo) over 心 (heart): stir the heart = provoke; rě sounds like the start of wreck
惹 stacks the phonetic 若 (ruò) on top of 心, the heart radical. Something that stirs up the heart provokes a reaction. The reading rě rhymes with the er in were.
惹 — grass 艹 + ear 耳 + heart 心 (phonetic 若)
惹 is a phono-semantic compound. The heart radical 心 at the bottom signals meaning related to feelings or actions affecting the mind, while the upper element 若 (ruò) supplies the sound, later softened to rě. It originally meant to provoke or stir up emotion, and still means to provoke, attract, or cause (trouble).
