An RFP vs. A RFP – Which is Correct?
Use “an RFP,” not “a RFP,” in standard English because the initial letter R is pronounced “ar,” a vowel sound. “RFP” means “request for proposals,” and the indefinite article follows pronunciation rather than spelling. Use “a request for proposals” when writing the term in full for maximum clarity and formality.
An RFP or A RFP – Which is Correct?
An RFP is correct in standard English. Although the abbreviation begins with the written consonant letter R, that letter is pronounced “ar,” which begins with a vowel sound. English therefore uses the article an: “an RFP.”
A RFP is generally considered grammatically incorrect because a is used before a consonant sound, while an is used before a vowel sound. The same rule applies to similar abbreviations, such as “an MBA,” “an HTML document,” and “an FDA regulation.”
The Best Trick to Remember the Difference
Say the abbreviation aloud as if it were a word: RFP begins with the sound “ar.” Because “ar” sounds like the beginning of “are,” and not like “ruh,” choose an. The swap test is also useful: replace “RFP” with “request for proposals.” Since you would say “a request for proposals,” remember that the abbreviation changes the article because its pronunciation begins with a vowel sound: “an RFP.”
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| an RFP | Indefinite article + noun phrase | One request for proposals | The agency issued an RFP for website development. |
| a RFP | Incorrect article usage | A commonly seen grammatical error | Write “an RFP,” not “a RFP.” |
How to Use An RFP
An RFP is used when referring to one request for proposals, a formal document that invites vendors or contractors to submit competing offers. The phrase is common in business, government procurement, information technology, construction, consulting, and nonprofit management. It has a formal, professional tone.
Use an RFP when the abbreviation is treated as a singular countable noun. It may follow verbs such as issue, publish, release, prepare, respond to, and evaluate.
Example 1: The city published an RFP for the construction of a new public library.
Example 2: Our company is preparing an RFP response for the software implementation project.
Example 3: The procurement team reviewed an RFP from a prospective technology partner.
Etymology of the Phrase An RFP
RFP is an initialism for request for proposals. The full phrase combines request, meaning an invitation or demand for information, with proposals, meaning submitted plans or offers. The abbreviation became especially common in modern business and public-sector procurement. Because each letter is pronounced separately as “ar-eff-pee,” the correct article is an.
The distinction also matters when naming the person who submits an RFP, as explained in Request vs. Requestor.
Related Concepts
Understanding pronunciation-based article choice makes it easier to use abbreviations and initialisms accurately in professional writing.
- Indefinite articles: The articles a and an refer to one nonspecific person, object, or concept. The choice depends on the following sound, not simply the following letter.
- Initialisms: An initialism is an abbreviation pronounced letter by letter, such as RFP, FBI, or MBA. When the first letter is pronounced with a vowel sound, use an.
- Vowel sounds: Words beginning with vowel sounds take an, including “an RFP,” “an hour,” and “an unusual request.” Words beginning with consonant sounds take a, including “a vendor” and “a proposal.”
- Countable nouns: An RFP refers to one document or procurement request, so it can be used with a singular indefinite article and a plural form: “several RFPs.”
Examples from Media and Literature
The phrase an RFP commonly appears in professional reporting, procurement notices, business communications, and fictional workplace dialogue.
- News reporting: A newspaper article about a city’s infrastructure plans might state, “The transportation department issued an RFP for a new rail station.”
- Government communication: A public procurement notice may announce, “The agency is accepting responses to an RFP for emergency-management services.”
