Answer, Reply, Respond – Difference, Examples & Quiz

Hello, English learners, and welcome to a new lesson. Today we are looking at three very common verbs that English learners often confuse: answer, reply, respond.

At first, they seem very similar because they all describe reacting to someone or something.

For example:

• He answered my question.
• He replied to my question.
• He responded to my question.

All three sentences are grammatically correct, but they do not sound exactly the same. They have different uses, different grammar patterns, and slightly different meanings.

The simple difference is this:

Answer usually means to give information or solve a question.

Reply means to say or write something back.

Respond means to react, often in a more general or formal way.

Let’s look at them carefully.

Answer

Answer means to give information after someone asks you a question. It can also mean to deal with a problem, solve something, or pick up the phone when it rings.

Answer is the most direct and practical of the three verbs.

Common uses of answer

• We often use answer with:
• questions
• exam questions
• problems
• riddles
• requests
• phone calls
• emails or messages, especially when we mean “give the required information”

Grammar pattern

Answer + object

Do not normally use to after answer when it has an object.

Correct: She answered my question.

Incorrect: She answered to my question.

Correct: I answered his email.

Incorrect: I answered to his email.

Reply

Reply means to say or write something back after someone has spoken or written to you. It focuses more on communication than on giving correct information.

Reply is especially common with:

• emails
• messages
• letters
• comments
• invitations
• formal communication
• conversations

Grammar pattern

Reply usually needs to before the person, message or thing you are replying to.

Correct: She replied to my email.

Incorrect: She replied my email.

Correct: He replied to my message.

Incorrect: He replied my message.

Correct: I replied to her question.

Incorrect: I replied her question.

In everyday English, answer is often more direct. Reply can sound a little more formal or careful, especially in writing.

Compare:

• I answered his email.
• I replied to his email.

Both are correct, but replied to his email sounds a little more focused on written communication.

Respond

Respond is broader than answer and reply. It means to react to something. The reaction can be spoken, written, emotional, physical, medical, political or practical.

This makes respond the most general of the three verbs.

Common uses of respond

We often use respond with:

• situations
• problems
• emergencies
• messages
• complaints
• criticism
• treatment
• medicine
• pressure
• changes
• requests
• danger

Grammar pattern

Respond is usually followed by to.

Correct: The company responded to the complaint.

Incorrect: The company responded the complaint.

Correct: The patient responded well to the treatment.

Incorrect: The patient responded the treatment.

Correct: She didn’t respond to my message.

Incorrect: She didn’t respond my message.

Quick Comparison: Answer, Reply, Respond

answer	give information or solve something	questions, phone calls, problems	answer something
reply	say or write something back	emails, messages, letters, comments	reply to something
respond	react in words, actions or feelings	situations, treatment, criticism, emergencies	respond to something

Common Mistakes

Mistake 1: Using answer to

Incorrect: She answered to my question.

Correct: She answered my question.

Incorrect: He answered to the email.

Correct: He answered the email.

But remember: as a noun, we say answer to.

Correct: I don’t know the answer to this question.

Mistake 2: Using reply without to

Incorrect: She replied my email.

Correct: She replied to my email.

Mistake 3: Using respond without to

Incorrect: The company responded my complaint.

Correct: The company responded to my complaint.

Mistake 4: Saying reply the phone

Incorrect: Can you reply the phone?

Correct: Can you answer the phone?

We answer the phone, not reply the phone.

Mistake 5: Using answer when respond sounds more natural

Less natural: The government answered to the crisis.

Better: The government responded to the crisis.

Less natural: The patient answered well to the treatment.

Correct: The patient responded well to the treatment.

Here, replied means he wrote back. Answer means he gave the required information.

Example 2
