Respond is a verb, and response is a noun. Use respond when someone does the answering or reacting, as in “Please respond by Friday.” Use response when you name the answer or reaction itself, as in “I am waiting for your response.” The two words are related but do different jobs.
They share a root and a similar meaning, so choosing between respond or response trips up many writers, especially in email and chat. This guide explains each word, shows how they work in sentences, and gives you simple tests, examples, and a short quiz to help you choose correctly every time.
Comparison Overview (Respond or Response)
The easiest way to separate the two words is to ask what the sentence needs. If it needs an action, use respond. If it needs a thing that can be received, sent, or waited for, use response.
- Respond is the action: “She will respond tomorrow.”
- Response is the result: “Her response was helpful.”
Both words are standard in American and British English. The spelling is the same in both varieties, and only the pronunciation of the vowel changes slightly by accent.
Definition of Respond
Respond is a verb. Merriam-Webster gives two main senses: to say something in return, and to react. It is usually followed by the preposition “to” when you name what you are answering or reacting to.
- To answer or reply: “The manager responded to my question within an hour.”
- To react: “Most patients respond well to this treatment.”
- To act in return: “The city responded quickly to the flood warning.”
Respond can also introduce reported speech: “He responded that he was already busy.” The verb forms are respond, responds, responded, and responding. A noun use of “respond” appears in some dictionaries, but it is rare and specialized, so avoid it in everyday writing.
Definition of Response
Response is a noun. It means an answer, a reply, or a reaction to something. It can be spoken, written, or physical.
- An answer: “I have not received a response from the school.”
- A reaction: “The crowd’s response was loud and warm.”
- A bodily reaction: “Shivering is the body’s response to cold.”
The plural is responses. Because response is a noun, it usually follows words such as a, the, your, no, any, or an adjective, and it is often followed by “to”: “Her response to the offer was polite.”
Main Differences Between Respond and Response
The main difference is grammatical function. Respond describes what someone does. Response names what is produced. Many errors come from using one word in the slot that belongs to the other.
Two other differences help as quick checks:
- Sound and spelling: Respond ends in the “d” sound and the letters -nd. Response ends in the “s” sound and the letters -nse.
- Pairing: Respond often takes a subject and “to.” Response often takes a determiner and “to.”
Comparison Table
| Feature | Respond | Response |
| Part of speech | Verb | Noun |
| Core meaning | To answer or react | An answer or reaction |
| Ending sound | /d/ | /s/ |
| Usual position | After a subject, “to,” “will,” “please,” or “can” | After “a,” “the,” “your,” “no,” or an adjective |
| Typical pattern | respond to + thing | response to + thing |
| Example | “I will respond today.” | “I sent my response today.” |
| Common mistake | Using it after “your” | Using it after “please” or “will” |
Grammar Guide
Grammar decides the choice here, not style. Neither word is “more formal” in the way people often claim. The only real question is whether the sentence needs a verb or a noun.
How each term is used in sentences
Respond works as the main verb of a clause:
- “The company responded to the complaint.”
- “Please respond when you are free.”
- “They are responding to every message.”
Response works as the subject, object, or complement of a clause:
- “Your response arrived this morning.” (subject)
- “I appreciated her response.” (object)
- “His only response was a smile.” (complement)
The phrase “in response to” is a fixed prepositional phrase meaning “as an answer to”: “In response to your request, we have updated the file.”
Common mistakes learners make
- Incorrect: Thank you for your respond.
Correct: Thank you for your response.
“Your” needs a noun, so response is required. - Incorrect: Please response to this email.
Correct: Please respond to this email.
After “please,” the sentence needs a verb. - Incorrect: I responded your message.
Correct: I responded to your message.
Respond takes “to” before the thing you answer. - Incorrect: She responses quickly.
Correct: She responds quickly.
The third-person verb form is responds. - Incorrect: I haven’t got a respond yet.
Correct: I haven’t got a response yet.
“A” signals a noun.
Simple rules to remember
- Do something? Respond. If a person or thing performs the action, use the verb.
- Receive something? Response. If you can send it, wait for it, or get it, use the noun.
- Check the ending. The verb ends in -nd and the noun ends in -nse.
- Swap test. If “react” fits, use respond. If “reaction” fits, use response.
Quick tips for writing and speaking
When writing, scan for the small words before the gap. “To,” “will,” “can,” “please,” and “did not” signal respond. “A,” “the,” “your,” “no,” and “quick” signal response.
When speaking, listen to the final sound. A hissing “s” at the end means the noun. A firm “d” means the verb. If you tend to mix them up in speech, slow down on the last syllable until the habit settles.
When to Use Each One
Use respond when the sentence needs an action:
- Asking for an answer: “Please respond by noon.”
- Describing a reaction: “Plants respond to sunlight by growing toward it.”
- Reporting what someone did: “The mayor responded with a short statement.”
Use response when the sentence needs a thing:
- Naming an answer: “I am still waiting for a response.”
- Describing a reaction: “The public response was positive.”
- Using fixed phrases: “in response to,” “response time,” “response rate,” “emergency response.”
When NOT to Use Each One
Do not use respond where a noun is needed. It sounds wrong after a, the, your, my, any, or no:
- Incorrect: “I got no respond from the landlord.”
- Correct: “I got no response from the landlord.”
Do not use response where a verb is needed. It cannot follow “will,” “can,” “should,” “to,” or “please”:
- Incorrect: “I will response tomorrow.”
- Correct: “I will respond tomorrow.”
The same logic fixes the phrase “no respond or response.” For a noun, write “no response”: “There was no response to my call.” For a verb, write “did not respond”: “The shop did not respond to my call.”
Which One to Use (Decision Guide)
Follow these steps when you are unsure:
- Look at the words just before the gap.
- If you see a, the, your, my, no, any, or an adjective, choose response.
- If you see to, will, can, should, please, did not, or a subject such as “she” or “they,” choose respond.
- Test with a swap: “react” fits the verb, and “reaction” fits the noun.
- Check the ending: -nd for the verb, -nse for the noun.
