usage note for suicide

In English, the verb suicide exists (e.g., Many teens who suicide have experienced abuse or bullying ), but its use is rare. Rather, the most common way to express the idea of taking one鈥檚 own life uses the noun suicide in the expressions to commit suicide or to attempt suicide .
However, the phrase commit suicide is discouraged by major editorial style guides, mental health professionals, and specialists in suicide prevention. The verb commit is associated with crime (in the justice system) and sin (in religion). Using such moralistic language deepens the emotional pain surrounding a suicide.
The verb phrases to die by suicide and to end one鈥檚 life are now preferred over the common expression commit suicide . The adjectives successful , unsuccessful , and failed are words that should be avoided when describing a suicide or suicide attempt, as is language that either romanticizes or stigmatizes the act.
Suicide is undeniably a hard subject to broach. It is okay to talk about suicide; studies show that discussing suicide with someone will not make that person suicidal or increase the likelihood of acting on suicidal ideation. But using language that criminalizes the act is insensitive to those whose lives have been touched by suicide.
