Reverse Each Word
Type or paste text below to reverse the letters of every word individually — word order stays the same, but each word reads backwards.
What Does "Reverse Each Word" Mean?
Reversing each word means taking every word in the text, mirroring its letters from last to first, and putting it back in the same position in the sentence. The word order stays completely unchanged — only the letters within each word are flipped.
| Input | Each Word Reversed |
|---|---|
hello world |
olleh dlrow |
Hello there Joe |
olleH ereht eoJ |
one two three |
eno owt eerht |
racecar level |
racecar level |
Notice racecar and level are palindromes — they read the same backwards as forwards, so reversing their letters produces no change.
How It Works
- Split the text on whitespace to get an array of words
- For each word, split into characters, reverse, and rejoin
- Join the reversed words back together with single spaces
In JavaScript: text.split(/\s+/).map(w => w.split('').reverse().join('')).join(' ')
How Is This Different From the Other Reverse Tools?
All three tools reverse something different:
| Tool | What reverses | What stays the same |
|---|---|---|
| Reverse Each Word (this tool) | Letters within each word | Word order |
| Reverse Words | Word order | Letters within each word |
| Reverse String | Every character in the entire string | Nothing — full reversal |
For example, with the input Hello World:
- Reverse each word →
olleH dlroW - Reverse words →
World Hello - Reverse string →
dlroW olleH
Common Uses
Word puzzles and games — Reversing each word creates a readable-looking but scrambled text that's fun for word puzzles. Unlike a full string reversal, sentence rhythm is preserved.
Encoding and obfuscation — Simple word-by-word reversal is used in some trivia games and puzzles as lightweight obfuscation. It's not encryption — reversing each word again restores the original.
Programming practice — This is a classic coding exercise that combines string splitting, array mapping, and character reversal. It tests more nuanced skills than a simple full string reverse.
Frequently Asked Questions
Are spaces and line breaks preserved?
Multiple spaces and line breaks between words are collapsed — words are split on any whitespace and rejoined with single spaces.
Does punctuation attached to a word get reversed with it?
Yes. Hello, becomes ,olleH — the comma is treated as part of the word. If you need punctuation-aware reversal, you'd need a more specialized tool.
Is this the same as a full string reverse?
No. A full string reverse of Hello World gives dlroW olleH — a complete character-for-character flip including the space. Reversing each word gives olleH dlroW, which keeps the space in the middle and only flips within each word.
