What Does Reinforce Mean?
The verb reinforce means to strengthen something, provide additional support, or make an idea, behavior, structure, or feeling stronger.
It can be used in both literal and figurative contexts.
For example, a physical structure can be reinforced with stronger materials. Similarly, an idea can be reinforced by evidence, and a positive behavior can be reinforced through encouragement.
Common meanings of reinforce
1. To make something physically stronger
A wall may be reinforced with steel to improve its strength and stability.
Example:
The engineers reinforced the bridge before allowing heavy vehicles to cross it.
2. To strengthen an idea or belief
Evidence can reinforce an argument or conclusion.
Example:

3. To encourage a behavior
Praise or rewards can reinforce desirable behavior.

Is Reenforce a Correct Word?
Reenforce does exist as a historical or variant spelling, but it is not the normal spelling used in modern standard English.
You may find reenforce in older texts, historical documents, dictionaries, or occasional modern writing. However, contemporary writers generally use reinforce.
This distinction is important because a word can appear in dictionaries or historical sources without being the best choice for everyday modern writing.
For practical purposes, if you are writing an essay, website article, report, email, resume, or professional document, use reinforce.
Why Does “Reenforce” Look Correct?
The confusion is understandable because English contains many words beginning with re-, such as:
- reconsider
- rebuild
- rewrite
- reconnect
- reestablish
Because reinforce sounds as though it might contain “re + enforce,” some writers naturally spell it reenforce.
However, the established modern spelling is reinforce.

Common Mistakes With Reinforce
One of the most common mistakes is simply choosing reenforce because it appears to match the pronunciation.
Mistake 1: Writing “reenforce”
Incorrect or nonstandard:
The new evidence reenforced his argument.
Preferred:
The new evidence reinforced his argument.
Mistake 2: Confusing reinforce with enforce
Although reinforce and enforce are related in appearance, they have different meanings.
Reinforce means to strengthen or support something.
Enforce means to make sure that a rule, law, or requirement is followed.
For example:
- The evidence reinforced her conclusion.
- The police enforced the law.
You can reinforce an argument, but you generally enforce a rule.
Mistake 3: Using the wrong spelling in formal writing
Even if readers understand reenforce, using it can make your writing appear less polished. For professional and academic content, consistency with standard modern spelling is the better choice.
Reinforce in American vs British English
There is no major American vs British spelling difference for this word.
Both American English and British English use reinforce as the standard spelling.
For example:
- American English: The results reinforce the findings.
- British English: The results reinforce the findings.
The spelling remains the same.
The confusion surrounding reenforce is therefore not primarily a difference between American and British English. Instead, it relates to an uncommon variant spelling that can occasionally appear in historical or less-standard usage.
Reinforce: Synonyms and Related Words
Knowing synonyms can help you understand the meaning and use of reinforce naturally.
Depending on context, suitable alternatives include:
- strengthen
- support
- bolster
- fortify
- enhance
- encourage
- confirm
- solidify
- emphasize

For example, bolster often means to support or improve something, while emphasize means to give particular importance to something. Reinforce can cover both physical strengthening and the strengthening of ideas, behaviors, or arguments.
How to Remember the Correct Spelling
A simple memory trick is to associate reinforce with the idea of reinforcing something by adding strength.
Think:
REINFORCE = STRENGTHEN
When you want to say that something becomes stronger, better supported, or more firmly established, reinforce is the spelling to choose.
