搭 is built from the 扌 (hand (left)), 艹 (grass (top)), and 合 components.
It belongs to a phonetic family with 答 and 塔 — they share the 合 component and the reading トウ.
A common word using 搭 is 搭載 (とうさい), meaning “loading (on a ship); equipping (an aircraft, car, etc.) with”.
Kanji that look similar include 提, 揚, 換, and 握.
