IPA: /kənˈfɪtɪər/
KK: /kənˈfɪtɪər/
A type of prayer in the Roman Catholic tradition where a person publicly admits their sins and asks for God's forgiveness.
During the Mass, the priest led the congregation in the confiteor to acknowledge their sins.
Confiteor is formed from "con-" (meaning together) and "fateri" (meaning to confess or admit). The word refers to the act of confessing together, often used in a religious context to acknowledge sins or faults.
Think of 'confessing together' — 'con-' means together, and 'fateri' means to admit or confess.
