Are “aid in dying," death with dignity,” and physician-assisted suicide different?

No. “aid in dying” or “death with dignity” are more socially tolerable terms for physician-assisted suicide. These terms are used by advocates of physician-assisted suicide in order to  avoid the use of the word “suicide”, which most people find objectionable. Webster’s Dictionary defines suicide as the “act or an instance of taking one’s own life voluntarily and intentionally especially by a person of years of discretion and of sound mind”.  Therefore, these terms mean nothing more than having a physician provide lethal medication to a patient who wishes to commit suicide.  "Sui" is the reflexive Latin root word that means "self," and "cide" is the Latin root that means "kill." Motivation and intention are not included in the definition of this basic term.
