搭档

partner
🤝 搭 (build/pair up) + 档 (file/slot) = pair into the same slot = partner
搭 means to join or pair up (as in 搭车 catch a ride); 档 means a slot, file, or grade. Together: two people slotted together for a task — a partner or teammate you cooperate with.
搭 — hand radical 扌 + 荅 (phonetic)
A semantic-phonetic compound. The hand radical 扌 signals the meaning—an action done with the hands, originally 'to join, attach, or build up.' The right side 荅 supplies the sound 'dā.' From 'joining together' it extended to 'putting up' (a tent), 'riding' (joining a vehicle), and 'matching as a pair.'
档 — wood radical 木 + 当 (dāng) phonetic
档 is a semantic-phonetic compound: 木 ('wood') signals the meaning, since the original referent was a wooden shelf or rack for storing files. 当 supplies the sound. From 'wooden file rack' the meaning extended to 'archive,' 'file,' and 'grade/category.'
