RSVPed and RSVP’d are both used to show the past tense of RSVP, meaning that someone responded to an invitation. RSVPed is often preferred because it is clearer and avoids the apostrophe
Have you ever written a sentence like “I RSVPed to the wedding” and wondered if it should be “I RSVP’d to the wedding” instead?
Both forms are used in English, so this question can be confusing.
The good news is that RSVPed and RSVP’d can both be used as the past tense of RSVP. The main difference is how writers add the past-tense ending to the abbreviation.
RSVPed looks like a normal English verb with -ed added.
RSVP’d keeps the abbreviation visible and adds ‘d.
Both mean that someone responded to an invitation.
Quick Answer: RSVPed or RSVP’d?
RSVPed and RSVP’d are both acceptable forms.
| Form | Meaning | Use |
| RSVP | Respond to an invitation | Present/base form |
| RSVPed | Responded to an invitation | Past tense |
| RSVP’d | Responded to an invitation | Past tense |
| RSVPing / RSVPing | Responding to an invitation | -ing form |
| RSVPs | Responses to invitations | Noun plural |
For example:
I RSVPed to the wedding.
or
I RSVP’d to the wedding.
Both sentences mean the same thing.
What Does RSVP Mean?
RSVP comes from the French phrase répondez s’il vous plaît, which means “please reply.”
You often see RSVP on:
- Wedding invitations
- Birthday invitations
- Dinner invitations
- Business events
- Conferences
- Meetings
- Parties
- Formal celebrations
When an invitation says:
Please RSVP by Friday.
It means the host wants you to tell them if you will attend.
RSVP can work as both a verb and a noun.
RSVP as a verb
Please RSVP by Monday.
Here, RSVP means respond to the invitation.
RSVP as a noun
We received 50 RSVPs.
Here, an RSVP means a response to an invitation.
What Does “RSVPed” Mean?
RSVPed is the past-tense form of RSVP.
It means someone already responded to an invitation.
For example:
I RSVPed to the party yesterday.
This means:
I responded to the party invitation yesterday.
You can also use RSVPed with other subjects:
She RSVPed to the wedding.
They RSVPed before the deadline.
Everyone RSVPed on time.
Have you RSVPed yet?
The form RSVPed treats RSVP much like an ordinary English verb.
What Does “RSVP’d” Mean?
RSVP’d has the same meaning.
The apostrophe appears before the d:
RSVP + ‘d = RSVP’d
For example:
I RSVP’d to the dinner.
She RSVP’d yesterday.
We RSVP’d as soon as we received the invitation.
There is no major difference in meaning between RSVPed and RSVP’d.
The main difference is visual style.
Why Are There Two Forms?
RSVP started as a French abbreviation, but English speakers began using it as a verb.
Once an abbreviation becomes a verb, writers have more than one way to add grammatical endings.
One approach is:
RSVP + ed = RSVPed
Another approach is:
RSVP + ‘d = RSVP’d
The first looks more like a normal English verb.
The second makes the original abbreviation easier to see.
That is why both forms appear in modern English.
Current dictionary sources support this broader usage. Cambridge gives examples with both RSVPed and RSVP’d, while Collins also lists both forms. (Cambridge Dictionary)
RSVPed vs. RSVP’d at a Glance
Here is the difference in the simplest possible way:
RSVPed
RSVP + ed
I RSVPed to the event.
RSVP’d
RSVP + ‘d
I RSVP’d to the event.
Meaning
Both mean:
I responded to the invitation.
So you do not need to learn two different meanings.
You only need to understand two different spelling styles.
Is RSVPed a Correct Word?
Yes.
RSVPed is an established form of the verb RSVP.
It is not simply a careless spelling or a typo.
For example:
We RSVPed to the conference.
This is a normal way to say that you responded to the conference invitation.
American Heritage lists RSVPed as an inflected verb form. (American Heritage Dictionary)
Cambridge also uses RSVPed in its dictionary examples. (Cambridge Dictionary)
Is RSVP’d a Correct Word?
Yes.
RSVP’d is also an established form.
For example:
She RSVP’d to the wedding last night.
It means:
She responded to the wedding invitation last night.
The apostrophe shows that the past-tense d has been added to the abbreviation.
Collins documents both RSVP’d and RSVPed in its English entries.
Which One Should You Use?
Since both forms are accepted, your choice can depend on style.
Use RSVPed if you want:
- A simple modern spelling
- A form that looks like a regular verb
- Clean digital writing
- A straightforward appearance
Example:
I RSVPed to the party.
Use RSVP’d if you want:
- To keep the abbreviation visually clear
- A traditional-looking form
- A style commonly seen on invitations and event writing
Example:
I RSVP’d to the party.
The important thing is consistency.
If you choose RSVPed in a document, there is usually no need to switch to RSVP’d later.
RSVPed or RSVP’d in Formal Writing
Both forms can appear in professional and formal communication.
For example:
All guests who RSVPed by Friday will receive confirmation.
Or:
All guests who RSVP’d by Friday will receive confirmation.
Both sentences are understandable and grammatical.
However, if you want to avoid any style debate, you can simply write:
All guests who responded to the invitation by Friday will receive confirmation.
This is often the clearest choice in very formal writing.
RSVP to or RSVP for?
Another common question is if you should say RSVP to or RSVP for.
In many situations, RSVP to is the natural construction when you mean responding to an invitation or event.
RSVP to
Please RSVP to the invitation.
I RSVP’d to the wedding.
She RSVPed to the conference.
You can also use RSVP for in contexts where the focus is the event or attendance:
I RSVP’d for the dinner.
She RSVPed for the conference.
Both constructions can occur, but RSVP to the invitation is especially clear when the invitation itself is the object.
What Is the Plural of RSVP?
When RSVP is used as a noun, the plural form is generally:
RSVPs
For example:
We received 100 RSVPs.
The event has already received many RSVPs.
Please check the RSVPs before preparing the seating plan.
Do not confuse this with the past tense.
Noun
We received 50 RSVPs.
Past-tense verb
Fifty guests RSVPed.
These are different grammatical jobs.
RSVP in Emails
RSVP is very common in email communication.
Invitation
Please RSVP by September 20.
Reply
I RSVP’d to the event yesterday.
Modern form
I RSVPed through the online form.
Formal alternative
I responded to the invitation yesterday.
All four sentences communicate the same basic idea.
RSVP in Business Communication
Businesses often use RSVP when organizing:
- Conferences
- Training sessions
- Networking events
- Webinars
- Meetings
- Company dinners
- Product launches
- Workshops
For example:
Please RSVP by Thursday so we can finalize the guest list.
Past tense:
Most of the invited clients have already RSVPed.
Or:
Most of the invited clients have already RSVP’d.
Both forms can work.
RSVP in Social and Casual Writing
You will also see these forms in texts and social media posts.
For example:
Just RSVPed to the party!
I RSVP’d already.
Have you RSVPed?
We haven’t RSVPed yet.
In very casual writing, some people simply say:
I replied to the invite.
That sounds natural and avoids the spelling question completely.
What About “RSVPing” and “RSVP’ing”?
The present participle can also be written in more than one way.
You may see:
RSVPing
or
RSVP’ing
For example:
People are RSVPing to the event.
You may also encounter:
People are RSVP’ing to the event.
Modern dictionary usage includes forms such as RSVPing, and dictionary sources also record the apostrophe form.
For clean modern writing, RSVPing is a simple option.
Common Mistakes With RSVP
Mistake 1: Writing “RSVPed’d”
❌ I RSVPed’d to the event.
This combines two different past-tense styles.
Use:
✅ I RSVPed to the event.
or
✅ I RSVP’d to the event.
Mistake 2: Writing “rsvped” in formal text
❌ I rsvped to the conference.
For polished writing, keep the abbreviation in uppercase:
✅ I RSVPed to the conference.
or
✅ I RSVP’d to the conference.
Mistake 3: Confusing RSVP and RSVPs
These have different jobs.
❌ We received 30 RSVP yesterday.
✅ We received 30 RSVPs yesterday.
But:
✅ Thirty guests RSVPed yesterday.
Mistake 4: Thinking RSVPed is always wrong
That is not true.
RSVPed is a documented and established form.
Mistake 5: Thinking RSVP’d is the only correct form
That is also too strict.
RSVP’d is established, but RSVPed is also used and documented.
RSVPed or RSVP’d: Example Sentences
Here are some natural examples.
RSVPed

RSVP’d
I RSVP’d to the wedding yesterday.
She RSVP’d before the deadline.
They have already RSVP’d.
Have you RSVP’d to the dinner?

Notice that the meaning does not change.
A Simple Memory Trick
You do not need to memorize a complicated rule.
Just remember:
RSVP + ED = RSVPed
RSVP + ‘D = RSVP’d
Both forms mean:
responded to an invitation.
If you forget which one to use, you can also write:
responded to the invitation
That phrase is always clear.
