confirm
To say that something is definitely true or to make an arrangement official.
Explanation at your level:
You use confirm when you say 'yes' to a plan. If you have a meeting, you say, 'I confirm I will be there.' It means you are sure. It is like saying 'I agree' or 'It is true.' You use it to make plans clear for everyone.
When you confirm something, you check that it is correct. For example, you can confirm your flight time or confirm your hotel room. It helps you feel sure about your plans. It is a very useful word for traveling and making appointments.
In an intermediate context, confirm is used to verify information. If you hear a rumor, you might look for facts to confirm it is true. It is also used in business to finalize agreements. For instance, 'Please confirm your attendance by Friday.' It shows you are organized and reliable.
At the B2 level, you use confirm to handle more complex situations. You might confirm a theory, confirm a suspicion, or confirm a booking. It suggests a higher level of professional communication. You should be comfortable using it in both passive and active voice, such as 'The appointment was confirmed by the secretary.'
Advanced learners use confirm to discuss validity and evidence. You might confirm the authenticity of a document or confirm a hypothesis in a research paper. It implies a rigorous process of verification. The word carries weight; it suggests that doubt has been removed through careful observation or official process.
At the mastery level, confirm can be used in nuanced ways to describe the solidification of beliefs or systemic processes. It can relate to the 'confirmation' of a social status or the 'confirmation' of a long-held cultural narrative. It is a word that bridges the gap between simple verification and the establishment of objective truth in academic and literary discourse.

- Confirm means to make sure.
- It is used for plans and facts.
- It is a versatile verb.
- It has a Latin root.
When you confirm something, you are basically saying, 'Yes, this is true,' or 'Yes, I will be there.' It is a very common word used to remove doubt from a situation.
Think of it as a seal of approval. If you are uncertain about a rumor, you look for facts to confirm it. If you have a dentist appointment, the office might call to confirm that you are still coming. It turns a 'maybe' into a 'definitely.'
Using this word makes your communication clear and reliable. It is essential in both business and daily social interactions because it helps people coordinate their lives without confusion.
The word confirm has a long and interesting journey. It comes from the Latin word confirmare, which is made of two parts: con- (meaning 'together' or 'completely') and firmare (meaning 'to make firm' or 'to strengthen').
It entered English through Old French in the 13th century. Originally, it had a strong religious meaning, often used in the context of the church rite of 'confirmation,' where a person's faith is made firm or strengthened.
Over time, the meaning broadened from spiritual strengthening to general verification. It is fascinating how a word that started as a way to describe building physical strength now helps us build social certainty in our digital world.
You will hear confirm used in many settings. In formal business, you might 'confirm an order' or 'confirm a reservation.' In casual conversation, you might simply ask a friend to 'confirm the time' for a movie.
Common collocations include confirm a suspicion, confirm a report, and confirm an appointment. It is a very versatile verb.
Note that we often use it with 'that' clauses: 'I can confirm that the package has arrived.' It is a neutral word, meaning it works just as well in a professional email as it does in a text message to your roommate.
While 'confirm' itself isn't always part of a fixed idiom, it is used in phrases that imply verification:
- Confirm the worst: To find out that a bad suspicion was actually true.
- Confirm the booking: A standard phrase for finalizing travel or hotel plans.
- Confirm the details: To double-check all the small parts of an agreement.
- Confirm by email: A common instruction to ensure there is a written record.
- Confirm one's identity: To prove who you are, often required at airports or banks.
Confirm is a regular verb. Its past tense and past participle are confirmed, and its present participle is confirming.
The IPA pronunciation is /kənˈfɜːrm/. The stress is on the second syllable: con-FIRM. It rhymes with words like firm, term, and worm.
A common mistake is to confuse it with 'affirm,' which is more about stating something strongly as a truth. Always remember that 'confirm' usually requires an external piece of evidence or a prior arrangement.
Fun Fact
It shares a root with the word 'firm' (as in a business).
