Other forms: psychiatrists
A psychiatrist is a doctor who specializes in emotional, behavioral, or mental disorders. Sigmund Freud is the founder of the field of psychiatry, pioneering psychoanalytic treatment.
The noun psychiatrist has Greek roots in psykhe, meaning mind, and iatreia, meaning healing, so the word psychiatrist is literally one who heals the mind. As opposed to a psychologist, who also offers psychotherapy, a psychiatrist is a medical doctor and, as such, can prescribe medication for things like depression and anxiety.
