Rein in vs. Reign in – Which is Correct?
The correct phrase is rein in, meaning to control, limit, or curb something, much like a rider uses reins to control a horse. Reign in is a common misspelling, likely due to phonetic similarity; “reign” refers to the period a monarch rules or the act of ruling, and it does not form a valid idiomatic expression with “in.”
Rein in or Reign in – Which is Correct?
When you want to express the idea of controlling, limiting, or bringing something under tighter management, the correct phrase to use is rein in. This idiom draws its meaning directly from the physical act of using “reins” – the straps attached to a bridle – to guide and control a horse. A rider pulls on the reins to slow down, stop, or direct the animal.
The phrase reign in is incorrect. It is a common phonetic error, where the word “reign” (meaning to rule as a monarch, or a period of rule) is mistakenly used instead of “rein.” While “reign” implies control, it does not combine with “in” to form the idiomatic expression for curbing or limiting. The root cause of this confusion is often that the two words sound identical when spoken aloud, leading to errors in writing.

| rein in | Phrasal Verb | To control, limit, or curb; to restrain. | The government needs to rein in its spending. |
| reign in | Incorrect | A common misspelling of “rein in.” | (Incorrect) He tried to reign in his anger. |
How to Use Rein in

Etymology of the word Rein in
The word “rein” comes from the Old French “reine,” which itself derived from the Latin “retina,” meaning “a strap, a band, a restraint.” This lineage clearly points to its connection with controlling or holding back. The phrasal verb “rein in” emerged from this literal meaning of using reins to control a horse, extending metaphorically to controlling other things. It has been in use in English as an idiom for centuries.
Related Concepts
Understanding the distinction between “rein in” and “reign in” highlights the importance of recognizing homophones and idiomatic expressions. Homophones are words that sound alike but have different spellings and meanings (e.g., rein/reign, to/too/two). Idiomatic expressions like “rein in” have a meaning that cannot be directly deduced from the individual words, making it crucial to use the correct word to convey the intended sense. Misusing a homophone within an idiom can completely change or nullify its meaning.

Frequently Asked Questions
Question 1: What is the primary difference between “rein” and “reign”?
“Rein” refers to the straps used to guide a horse, or metaphorically, to control or limit. “Reign” refers to the period or act of ruling as a monarch. They are homophones but have distinct meanings and spellings.
Question 2: Why is “reign in” considered incorrect?
“Reign in” is incorrect because “reign” does not combine with “in” to form a recognized English idiom with the meaning of control or limitation. The correct idiom is “rein in,” stemming from the literal use of horse reins.
Question 3: Can “reign” be used with “in” in any context?
While “reign” can be used in sentences with the preposition “in” (e.g., “The king’s reign in the north was peaceful”), it does not form a phrasal verb meaning “to control” in the same way “rein in” does. The two words are not interchangeable in this idiomatic context.
Conclusion
The distinction between “rein in” and “reign in” is a clear example of how subtle differences in spelling can drastically alter meaning. To correctly convey the idea of controlling, limiting, or curbing something, always use rein in. Remember the image of a rider pulling on horse “reins” to keep this correct usage firmly in mind. Opting for “reign in” is a common error that can detract from the clarity and professionalism of your writing.
