If you greet your bus driver every day by saying, "Good Morning, Ms. Smith!" then you're familiar with honorifics, the respectful titles we add to people's names. In Ms. Smith's case, the honorific is Ms.
The most common honorifics in English are the ones we put in front of names, like Mr., Dr., and Reverend. There are military honorifics such as Captain and General, and religious honorifics, including Rabbi, Father, and Imam. Some honorifics come at the end of a person's name: "Mateo Garcia, PhD," and "Angela Smith, DDS," for example. The word honorific is also an adjective meaning "showing respect," as in an honorific award or an honorific title.
