復旧 and 回復: restoring infrastructure and recovering a condition
Read the start of bridge restoration, restored power, gradual strength recovery, and ongoing sales recovery through their objects and stages.
Bridge work and the return of power
壊れた橋の復旧作業が始まった。 reports work beginning to restore a broken bridge. 復旧, read ふっきゅう, concerns restoration of the bridge's function, while 始まった identifies the start of the work.
電力が復旧すると、町に明かりが戻った。 reports the lights returning across the town when power was restored. This supplies restoration and its result, unlike the bridge sentence that supplies the start of restoration work.
Recovery of strength and sales
休養を取り、体力が少しずつ回復した。 reports strength gradually recovering after rest. 回復, read かいふく, concerns an improving condition, with 少しずつ preserving the gradual extent.
店の売り上げはゆっくり回復している。 says that the store's sales are slowly recovering. 回復している describes an ongoing state; no figure establishes full return to an earlier sales level.
