Reign, rein, and rain sound identical, but their meanings are completely different. Knowing which one to use will help you avoid very common mistakes.
Reign refers to power, control, or the period when a ruler (king, queen, leader) is in charge.
Rein refers to the straps used to control a horse. We also use it for control in general: you can tighten or loosen the reins.
Rain is simply the water that falls from the sky.
