The left pedal on a bike typically has a left-hand thread.

The left pedal is the one with the left-hand thread.
The correct thread direction for installing bike pedals is to turn the right pedal clockwise and the left pedal counterclockwise.
You unscrew them( remember that the left one has a left-hand thread) and measure the diameter of the threaded end with a vernier caliper. Should be either 9/16"(14.3 mm) or 1/2" (12.7 mm)
The purpose of a bike pedal reverse thread is to prevent the pedal from unscrewing while riding. This means that the left pedal has a reverse thread, so it tightens in the opposite direction compared to the right pedal. This affects the installation and removal of pedals on a bicycle because it requires turning the left pedal counterclockwise to tighten it, and turning the right pedal clockwise to tighten it. This can be confusing for some people, but it ensures that the pedals stay securely attached to the bike during use.
If it's the pedal that's been damaged there's no fix that's as cheap and simple as replacing the pedal. But usually it's the crankarm that's damaged. The right side crank has a fairly common thread, and can be repaired with a heli-coil insert. The left side has a left-hand thread, and the only ones likely to have the tools to repair that is a bicycle store. If it's a department store bike replacing the crank might be a cheaper option.
The left pedal has a reverse thread. It'll come off if you turn it clockwise. It can be stuck pretty bad, so make sure you've got the direction right.
