In the Catechism what does the abbreviation "cf." mean?

I am a “cradle Catholic” that recently returned to the Church after being a lapsed Catholic for many years. Upon returning to the Faith, I came to realize that there is a great deal that I don’t know about Church teaching. I bought a few books, including The Catechism of the Catholic Church, which I am now studying.

In several places I have come across the abbreviation “cf.”, which is almost always followed by a reference to Sacred Scripture or some other reference. (e.g., “cf. Lk 22:32” or “cf. St. Ignatius of Antioch, Ad Trall, 3,1”) This may be a dumb question, but what does the abbreviation “cf.” mean?

Thank you.

cf. is an abbreviation for the Latin word confer (English for compare). Basically, it’s pointing to another reference. God bless you.
