Grandma went to buy groceries with a basket on her arm.
Tips
usage
挎 means carrying something with the strap over your arm or shoulder — bags, baskets, cameras. 挎包 (kuàbāo) = shoulder bag / crossbody bag. Don't confuse with 跨 (kuà, to stride/straddle), which uses the foot radical.
扌 is the left-side simplified hand radical. It marks 挎 as a hand-and-arm action — here, hooking something over the arm or shoulder, the way a satchel hangs from a forearm or a basket rides the elbow. Family includes 挂 (hang), 拎 (carry by handle), 抱 (embrace), 扛 (shoulder).
夸 (kuā) supplies the sound — initial preserved, rime preserved, tone shifted to fourth (kuà). Same phonetic powers 跨 (stride), 垮 (collapse), 胯 (hip), 侉 (vulgar) — all share a faint flavour of stretching or spanning, which fits the spread-elbow gesture of carrying on the arm.
