RSVPed or RSVP’d: Which Is Correct?

When writing about replying to an invitation, you may hesitate between RSVPed and RSVP’d. Both forms are built from the abbreviation RSVP, which comes from the French répondez s’il vous plaît, meaning “please reply.” The confusion arises because abbreviations do not always follow ordinary English spelling patterns when they become verbs. The good news is that you do not have to treat one of these forms as an outright spelling mistake: both RSVPed and RSVP’d are established forms. The choice mainly comes down to style and consistency.

RSVPed or RSVP’d: Which Form Is Correct?

Both forms can be used:

• RSVPed — correct and established
• RSVP’d — correct and established

For example:

I RSVPed to the wedding yesterday.

or:

I RSVP’d to the wedding yesterday.

Both sentences mean that the speaker responded to the wedding invitation.

The difference is primarily how the past-tense ending is attached to the abbreviation. In RSVP’d, the apostrophe separates the abbreviation from d. In RSVPed, the abbreviation is treated as the base of an ordinary English verb.

Major dictionaries document both patterns. Cambridge Dictionary uses RSVPed in an example and also gives examples using RSVP’d, while other dictionary sources list the forms among the inflections of RSVP.

Quick comparison

Form	Correct?	Typical use
RSVP	Yes	Present/base form
RSVPed	Yes	Past tense/past participle
RSVP’d	Yes	Past tense/past participle
RSVPing	Yes	Present participle/gerund
RSVPs	Yes	Third-person singular or plural noun, depending on context
RSVPd	Generally avoid	Awkward/nonstandard-looking form

The important point is that RSVPed is not simply a misspelling of RSVP’d.

What Does RSVP Mean?

RSVP is an abbreviation of the French phrase répondez s’il vous plaît, traditionally translated as “please reply.”

In English, it is commonly found on invitations:

Please RSVP by October 10.

This asks the recipient to tell the host whether they will attend.

RSVP can function as both a noun and a verb.

RSVP as a noun

We received 80 RSVPs for the dinner.

Here, RSVPs means responses to the invitation.

RSVP as a verb

Please RSVP by Friday.

Here, RSVP means “respond to the invitation.”

Once the abbreviation is used as a verb, it can take normal grammatical forms:

She RSVPed yesterday.

They RSVP’d last week.

What Does “RSVPed” Mean?

RSVPed is the past tense and past participle form of RSVP.

It means that someone responded to an invitation, usually by indicating whether they will attend.

For example:

I RSVPed to the birthday party.

This means:

I responded to the birthday invitation.

Another example:

Everyone who RSVPed received a confirmation email.

The word does not have a separate meaning from RSVP’d. The two forms describe the same action.

What Does “RSVP’d” Mean?

RSVP’d also means responded to an invitation.

The apostrophe represents the addition of the past-tense ending -d to the abbreviation:

RSVP + ’d → RSVP’d

For example:

Maria RSVP’d to the conference invitation.

This means Maria responded to the invitation.

The apostrophe can make the structure visually clearer because the reader can immediately see the abbreviation RSVP followed by the past-tense ending.

However, that does not make RSVPed incorrect. Both forms are established in English usage.

Why Are RSVPed and RSVP’d Both Used?

The difference comes from how writers treat the abbreviation when turning it into a verb.

With RSVP’d, the original abbreviation remains visually separate:

RSVP + ’d

With RSVPed, the abbreviation is incorporated into the spelling of the verb:

RSVP + ed

English contains many examples of abbreviations and initialisms becoming ordinary words or verbs. Once an abbreviation functions as a verb, writers may use different approaches when adding grammatical endings.

That is why you can encounter both:

She RSVP’d immediately.

and:

She RSVPed immediately.

Neither sentence requires a different interpretation.

Which should you choose?

If you want to preserve the abbreviation clearly, RSVP’d is a perfectly reasonable choice.

If you prefer a form that looks more like a regular English verb, RSVPed is also acceptable.

The most important thing is to choose one style and use it consistently within a document.

Do You Say “RSVP to” or “RSVP at”?

When you are talking about responding to an invitation or event, RSVP to is generally the natural construction.

For example:

Please RSVP to the invitation by Friday.

Did you RSVP to the wedding?

I already RSVPed to the dinner.

Here, to introduces the invitation, event, or request that someone is responding to.

When “RSVP at” makes sense

RSVP at can be appropriate when at introduces a location, contact point, or means for submitting the response.

For example:

Please RSVP at the email address provided below.

You can RSVP at the number printed on the invitation.

However, there are often more natural ways to express this:

Please RSVP to Jane at the email address below.

or:

Please RSVP by email.

So RSVP at is not automatically ungrammatical, but it does not replace RSVP to in every situation.

RSVP To or RSVP For?

These two prepositions can communicate different ideas.

RSVP to

Use RSVP to when referring to the invitation, event, or request being answered.

I RSVP’d to the wedding invitation.

Have you RSVPed to the dinner?

RSVP for

Use RSVP for when someone is responding on behalf of another person.

Could you RSVP for me?

John RSVP’d for his parents.

The distinction is useful because the preposition depends on what you are trying to express.

Compare:

I RSVP’d to the invitation.

This tells us what was answered.

My assistant RSVP’d for me.

This tells us on whose behalf the response was made.

How Do You Pronounce RSVP?

RSVP is normally pronounced by saying the individual letters:

R-S-V-P

It is not usually pronounced as one ordinary English word.

For example:

Please RSVP by Thursday.

In speech, RSVP is pronounced approximately:

“R-S-V-P”

The pronunciation is therefore straightforward even though the written abbreviation comes from French.

How Do You Pronounce RSVPed?

When RSVP is used as a verb in the past tense, the pronunciation follows the abbreviation plus the past-tense ending.

RSVPed can be thought of as:

“R-S-V-Ped”

The important part is that RSVP itself continues to be pronounced as the individual letters.

Similarly, RSVP’d is pronounced as the abbreviation followed by the past-tense sound.

In ordinary conversation, someone might avoid the slightly awkward-looking construction altogether and simply say:

I replied to the invitation.

That does not mean either written form is incorrect; it is simply an alternative phrasing.

Examples in Sentences

Here are natural examples using both forms.

Using RSVPed

I RSVPed to the wedding last night.

She RSVPed as soon as she received the invitation.

Have you RSVPed to the conference?

Everyone who RSVPed was added to the guest list.

Using RSVP’d

I RSVP’d to the wedding last night.

She RSVP’d as soon as she received the invitation.

Have you RSVP’d to the conference?

Everyone who RSVP’d was added to the guest list.

The meaning remains the same in each pair.

Present tense

Please RSVP by Monday.

We need everyone to RSVP before making the final arrangements.

Noun

We are still waiting for several RSVPs.

Here, RSVPs refers to the responses themselves rather than the action of responding.

Is “RSVPed” Okay in Formal Writing?

Yes, RSVPed is an acceptable form, and it is documented in dictionary usage.

However, style preferences can differ. Some editors and organizations may prefer RSVP’d because the apostrophe makes the abbreviation more visually recognizable.

For highly formal writing, you can also avoid the issue entirely by using responded:

Please respond to the invitation by Friday.

She responded to the invitation yesterday.

That wording is especially useful when clarity matters more than preserving the abbreviation.

For everyday invitations, emails, event notices, and informal professional communication, either RSVPed or RSVP’d can work.

Common Mistakes to Avoid

1. Assuming RSVPed is always wrong

It is not. RSVPed is an established form and appears in dictionary usage.

2. Assuming RSVP’d is the only possible spelling

It is also not necessary to make that claim. RSVP’d is accepted, but so is RSVPed.

3. Using “RSVP to” incorrectly

When you mean responding to an invitation or event, to is usually the natural choice:

Please RSVP to the invitation.

4. Confusing RSVP with the response itself

Compare:

Please RSVP by Friday.

Here, RSVP is a verb.

We received 50 RSVPs.

Here, RSVP is being used as a noun.

5. Writing “RSVPd”

The form RSVPd is best avoided. It removes the vowel from the usual past-tense ending and looks considerably less natural than RSVPed or RSVP’d.

Easy Way to Remember the Difference

Think of RSVP as an abbreviation that can behave like a verb.

For the past tense, you have two established choices:

RSVP + ed = RSVPed

RSVP + ’d = RSVP’d

Both mean:

responded to an invitation.

For the preposition, remember:

RSVP to the invitation.

If you are talking about the person responding on someone else’s behalf, RSVP for may be appropriate:

RSVP for me.

FAQ

Is RSVPed a correct word?

Yes. RSVPed is an established past-tense form of the verb RSVP. Major dictionary sources document its use. RSVP’d is also an accepted form, so RSVPed should not automatically be treated as a spelling error.

Is RSVP’d or RSVPed more correct?

Neither needs to be considered universally more correct. Both forms are used for the past tense of RSVP. RSVP’d preserves the abbreviation more visibly, while RSVPed treats it like a regular verb with an -ed ending.

Do you say RSVP to or RSVP at?

When referring to an invitation or event, RSVP to is generally the natural choice: “Please RSVP to the invitation.” RSVP at can be used when at introduces a contact point or method, such as an email address or telephone number.

How do you pronounce RSVP?

RSVP is normally pronounced by saying its four letters: R-S-V-P. The abbreviation is not usually pronounced as a single word.

Is RSVP a verb or a noun?

It can be either. As a verb, it means to respond to an invitation: “Please RSVP by Friday.” As a noun, it refers to a response: “We received 50 RSVPs.”

Is RSVP’d acceptable in formal writing?

Yes, although style preferences vary. RSVP’d is an established form. If you want the most straightforward wording in formal prose, you can also use responded to the invitation.

The Bottom Line

RSVPed and RSVP’d are both acceptable ways to write the past tense of RSVP. The apostrophe in RSVP’d highlights the abbreviation, while RSVPed uses the standard -ed spelling pattern for a verb. When talking about responding to an invitation, RSVP to is usually the natural construction.
