復 is built from the 彳 (step / going) and 复 (return (top of 復)) components.
It belongs to a phonetic family with 複, 腹, and 覆 — they share the 复 component and the reading フク.
A common word using 復 is 復習 (ふくしゅう), meaning “review (of lessons), revision”.
Don't confuse it with 複, 腹, and 覆 — 彳 return, 衤 duplicate, 月 belly, 覀 cover
