Anti-reverse
The one-way clutch that stops the handle spinning backward, so the rod loads instantly when you set the hook.
Without it, a hookset would first take up whatever backward play exists in the handle before any force reached the fish. Anti-reverse locks the handle in one direction so the rod loads the moment you sweep it.
Older reels used a ratcheting dog and a switch to turn the feature off, which let you back-reel: give line by turning the handle backward instead of relying on the drag. Some anglers still prefer that on light line. Most modern reels use a solid one-way roller bearing with no switch at all, because it gives zero back-play and there is nothing to wear out or click.
A reel that has developed a little backward wobble is telling you the clutch is worn. It is repairable but not usually worth it on a budget reel.
Grab the spool and try to turn the handle backward. Any play you feel there is play you will lose on the hookset.
