Reverse Words Online — Word Reverser & Sentence Flipper

Reverse Word Order keeps each word's spelling intact but flips their sequence — the last word moves to the first position, the second-last to the second position, and so on. For example: "The quick brown fox" → "fox brown quick The". The letters inside each word are unchanged. Reverse Letters in Words keeps the word positions intact but flips the letter sequence inside each word — so "Hello" becomes "olleH". For example: "The quick brown fox" → "ehT kciuq nworb xof". The words are still in their original left-to-right order but each word is a mirror of itself.

Sentence Order reversal flips the sequence of sentences in your input text, treating each sentence as an atomic unit. The tool identifies sentence boundaries by detecting terminal punctuation — periods, exclamation marks, and question marks — and reverses the order of the resulting sentence array. For example: "I went to the shop. I bought milk. I came home." → "I came home. I bought milk. I went to the shop." The words within each sentence remain in their original order and the punctuation stays attached to each sentence correctly. This is useful for studying narrative structure, creating reversed story prompts, or testing reading comprehension with reversed paragraph sequences.

Every Nth Word mode divides the word sequence into chunks of exactly N words and reverses the word order within each chunk, while leaving the chunk boundaries in their original positions. For example, with N=3 and text "A B C D E F", the tool groups words as [A,B,C] and [D,E,F], then reverses each group: "C B A F E D". With N=2 this is equivalent to the Swap Adjacent Words mode. This is useful for creating scrambled text that is locally disorganised (for NLP model testing, reading exercises, or puzzle generation) while keeping the text loosely comprehensible since each group is still in the original relative position.

Rotate performs a circular shift of the word sequence. With direction Right (first → last) and a rotation of 1, the first word moves to the last position and all other words shift left. With direction Left (last → first), the last word moves to the first position. For example: rotating "A B C D E" right by 2 gives "C D E A B". Rotating right by 1 is equivalent to moving the first word to the end. You can set the rotation count to any number — the result wraps around modulo the word count. This is useful for creating circular reading exercises, rotating scheduled lists, or testing different word sequence starting points.

When word order is reversed, the word that was originally capitalised at the start of a sentence often ends up in the middle or at the end of the output, while a lowercase word from the middle of the original is now first. Fix capitalisation corrects this automatically: it upper-cases the first letter of the output string (and of each sentence after a sentence boundary if sentence detection is enabled) and lower-cases any word in the middle or end that was originally capitalised only because it was at the start of a sentence. Note: words that are always capitalised (proper nouns like "London", "John", etc.) are not changed because the tool cannot distinguish them from sentence-initial capitalisation.

The three punctuation modes handle commas, periods, exclamation marks, question marks, colons, and semicolons attached to words differently. Attached to word (default): the punctuation moves with the word it was attached to. For example "Hello, world!" reversed becomes "world! Hello,". Stay in place: punctuation is stripped from words before reversing, then re-inserted at its original position in the output. "Hello, world!" reversed becomes "world, Hello!". Strip punctuation: all punctuation is removed before reversal and does not appear in the output. This produces the cleanest word sequence but loses all punctuation.

When enabled (the default), the tool treats each line of your input as a separate unit for word reversal. Words in line 1 are only reversed within line 1; they never mix with words in line 2 or line 3. This is the expected behaviour for most use cases — reversing a list where each line is an independent item. When disabled, the entire multi-line text is treated as one continuous word stream: all words from all lines are collected, reversed as a single sequence, and then re-wrapped to the original line lengths. This can produce unexpected results for multi-line content but may be useful for very specific scrambling needs.
