Redo means to do something again. You redo a task when the first attempt was not good enough, or when something needs to be repeated. In computers, redo also means restoring an action you just undid.
The word works as a verb and a noun. As a verb, you redo your homework. As a noun, a redo is a second try, such as a “do-over” in a game. Knowing both uses clears up most confusion.
What Does Redo Mean?
The simplest definition: to do again, often to fix or improve the first attempt.
The word has three main meanings.
Meaning 1: To do something over again
This is the everyday meaning. The first attempt failed, was incomplete, or could be better.
- “I had to redo the whole report.”
Meaning 2: To decorate or renovate
Here, redo means to refresh a space, a style, or an appearance.
- “They redid the kitchen last spring.”
- “She redid her hair before the party.”
Meaning 3: To restore an undone action (computers)
In software, redo reverses an undo command. It brings back the change you just took away.
- “I clicked undo by mistake, so I hit redo.”
💡 Quick tip: If you can replace the word with “do again,” you are using it correctly.

Verb forms of redo
Redo is an irregular verb. It follows the same pattern as “do.”
| Form | Word | Example |
| Base form | redo | “I will redo it.” |
| Third person singular | redoes | “She redoes her work carefully.” |
| Past tense | redid | “He redid the sketch.” |
| Past participle | redone | “The floors have been redone.” |
| Present participle | redoing | “We are redoing the website.” |
⚠️ Common mistake: Many people write “redoed.” That is not standard English. The correct past tense is “redid.”
Is it “redo” or “re-do”?
Standard American English writes it as one word: redo. Some people write “re-do” with a hyphen, but major dictionaries list the closed form. Use “redo” in formal and everyday writing.
Sentence structure
Redo is a transitive verb. That means it needs an object.
- Subject + redo + object
- “The students redid the experiment.”
You usually say what is being redone. “I redid” alone sounds incomplete.
How to Pronounce Redo
The stress changes depending on the part of speech.
| Part of speech | Stress | IPA (American) | Sounds like |
| Verb | Second syllable | /riːˈduː/ | ree-DOO |
| Noun | First syllable | /ˈriːduː/ | REE-doo |
The noun and verb sound very close in everyday speech. Most people will understand you either way.
Redo Meaning in Computers
In software, redo is a command. It reverses the last undo.
Think of it as a timeline. Undo moves you backward one step. Redo moves you forward one step.
Undo vs redo
| Command | What it does | Example |
| Undo | Reverses your last action | You delete a paragraph, then undo to bring it back |
| Redo | Restores the action you undid | You undo the deletion, then redo to delete it again |
Redo shortcuts
| System | Common redo shortcut |
| Windows | Ctrl + Y |
| Mac | Command + Shift + Z |
| Many apps (Windows and Linux) | Ctrl + Shift + Z |
Shortcuts can vary by program, so check the Edit menu if one does not work. In Microsoft Word, F4 also repeats your last action.
What does “nothing to undo, nothing to redo” mean?
Some apps show a message like this. It means you have not made any changes yet, or the history has been cleared. The undo and redo buttons stay gray until there is something to reverse.
💡 Tip: Redo only works right after an undo. If you make a new edit after undoing, the redo history is usually erased.
Redo Meaning in Everyday Sentences

- Work: “The client asked us to redo the logo.”
- School: “Can I redo the quiz?”

- “You cannot redo the past.” Here it means that time cannot be repeated.

Redo in Different Contexts
In business and workplace use
Managers use redo to ask for corrections. It can sound direct, so many people soften it: “Could you take another pass at this?”
In science and lab settings
Some lab and medical notes use shorthand with the word redo. This usually means a test or process must be repeated, for example when a sample was unusable. Abbreviations differ from lab to lab, so the exact meaning depends on that lab’s own system. If you see such a note, ask the lab or the clinician who wrote it.
In maintenance and technical work
In maintenance records, “redo” generally flags a job that needs to be performed again. As with lab notes, the exact meaning depends on the workplace’s own conventions.
In games and sports
A redo is a do-over. It is informal, and it is common in casual play. Official rules usually use terms like “replay” or “retake” instead.
In design and editing
Designers use redo to mean rework. “Redo the layout” can mean a full rebuild, not just a small fix.

Origin of the Word Redo
Redo is built from two parts: the prefix re- and the verb do.
- Re- comes from Latin and means “again” or “back.”
- Do comes from Old English.
English has many words built this way, such as rewrite, rebuild, and reopen. Redo follows the same pattern. Its meaning has stayed close to its parts: to do again.
The computing sense came later, when software began to include undo and redo commands.

Common Mistakes with Redo
Mistake 1: Using the wrong past tense
❌ Incorrect: “I redoed the report.”
✅ Correct: “I redid the report.”
Redo is irregular, just like do and did.
Mistake 2: Mixing up redo and redone
❌ Incorrect: “I have redid it.”
✅ Correct: “I have redone it.”
After “have,” use the past participle.
Mistake 3: Confusing redo with redouble
❌ Incorrect: “We will redo our efforts.”
✅ Correct: “We will redouble our efforts.”
Redouble means to increase, not to repeat.
Mistake 4: Leaving out the object
❌ Incorrect: “Please redo.”
✅ Correct: “Please redo the form.”
Redo needs to say what is being done again.
Mistake 5: Mixing up undo and redo in software
Undo steps back. Redo steps forward. Pressing the wrong one is a very common slip.
Re Do or Redo?
A common question is whether to write “re do” as two words. The answer is no. Use redo as one word. Writing “re do” is a spelling error. The hyphenated “re-do” appears sometimes but is less standard.
