🗂️ jià = frame/rack; measure word for shelves, planes, pianos
架 means a frame or rack, and serves as the measure word for things built on a frame: 一架飞机 (a plane), 一架钢琴 (a piano), 一架书 (a shelf of books). Top 加 (jiā) gives the sound; bottom 木 (wood) shows it's a wooden structure.
架 — wood 木 + add 加 (phonetic)
A semantic-phonetic compound: 木 (wood) gives the meaning, since a 架 is a wooden frame, rack, or shelf used to support things. 加 (jiā) supplies the sound. From 'wooden frame' it extended to verbs like 'to set up,' 'to prop up,' and to a measure word for framed objects such as airplanes.
