莜

Top grass radical - the 3-stroke compressed form of 艸. The indexing radical, anchors 莜 in the botanical family of 麦 wheat, 草 grass, 苗 seedling. Marks 莜 as a plant - specifically 莜麦 naked oats (Avena nuda), a hardy cereal long grown in north Chinese highlands and central to Shanxi cuisine (莜面 oat noodles).

Bottom 攸 supplies the sound - yōu shifting to yóu with tone change. Pure phonetic role; the literary 'distant' meaning of 攸 contributes nothing semantically. 攸 itself is a 7-stroke compound (person + stream-line + tapping hand). The simpler 莜 lets you reuse a less common phonetic component cleanly.
