confirmation
"Confirmation" is a satisfying word to know — it covers the idea of making something certain or official. It has a few closely related meanings, from everyday use to religious contexts. Here are the most common ones.
When you confirm that something is true or correct, the act of doing that — or the message/evidence that proves it — is called a confirmation. Think of it as the moment when a 'maybe' becomes a 'yes, definitely'.

She nodded as a confirmation that she understood the instructions.
In more formal situations, a confirmation is an official statement that something has been accepted, approved, or agreed upon. For example, after you book a hotel, the hotel sends you a confirmation — a document saying 'yes, your booking is real and accepted'.
business, law, formal settings · Modern, widely used
Sometimes 'confirmation' means something that makes you feel even more sure about what you already believed. It is not new information — it just supports what you thought. For example, if you suspected your friend was upset and then they stop answering your messages, that feels like a confirmation of your suspicion.

In Christianity, Confirmation is a special ceremony where a person — usually a teenager — formally commits to their faith. It is seen as completing or 'confirming' the promises made at their baptism. This is a very specific use of the word, tied to religious tradition.
