A confession is a signed statement by someone in which they admit that they have committed a particular crime.

Confession is the act of admitting that you have done something that you are ashamed of or embarrassed about.

If you make a confession of your beliefs or feelings, you publicly tell people that this is what you believe or feel.

In the Catholic church and in some other churches, if you go to confession, you privately tell a priest about your sins and ask for forgiveness.
