Rain, reign, and rein. They may seem simple words, but their similarity in sound can cause so much confusion, especially for writers. I always see these three words commonly misused or misspelled in indie books, leading to misunderstandings and sometimes even hilarious situations. So, I’ll delve into the differences between rain, reign, and rein and provide examples of how you use them correctly.

Reigns vs. Reins vs. Rains

Rain vs. Rein vs. Reign Difference in Definition Spelling

Let’s start with the most commonly confused pair: reigns and reins. Reigns refer to the period when a monarch rules a country or kingdom. Reins are the straps or ropes used to control a horse.

Meanwhile, rain is just the water that falls from the sky in droplets. So, unless you’re talking about a horse-drawn carriage during a royal procession in the rain, it’s very unlikely you’ll need to use all three words in one sentence. Although…

I pulled back on the reins of the horse as I saw rain falling over the kingdom where the evil queen reigns. I did it!

How Do You Spell Rain?

It’s just r-a-i-n if you mean the water that falls from the sky. But it’s r-e-i-g-n if you’re talking about ruling over something, and r-e-i-n for referring to a horse leash or scaling back on something.

Is It Reign in or Rein In?

Another common question I hear all the time is whether we should use “reign in” or “rein in” when talking about scaling something back or pulling back on a horse.

The correct phrase is “rein in,” which means to control or limit something. It comes from horseback riding, where leather reins are used to control a horse’s movements. So, if you need to control anything at all, remember to “rein it in,” not “reign it in.”

Just think of the popular TV show Reign. It’s about kings and queens ruling over kingdoms (and a bunch of other subplots), but just imagine the way the title looks whenever you need to remember which word is used to describe ruling over something.

For remembering the definition of rein, I always think of reindeer, which has the word rein in it.

Homonyms of Rain

Yes, rain is a homonym, meaning it has multiple meanings spelled and pronounced the same way. However, its homophones rein and reign don’t have homonyms.

The word “rain” can mean a shower of something other than water, like “a rain of arrows” or “a rain of criticism.” But you can also use it as a verb to describe the act of showering, like “to rain down on.”

Reign Homophones

Rein, rain, and reign are each other’s homophones, meaning they’re words that sound alike but have different definitions.

Rain, Reign, and Rein Pronunciations

Despite their differences in how they’re spelled and what they mean, rain, reign, and rein all have the same pronunciation. You should say each of them as rayn with a long “a” sound.
