In the mental health settings where I've worked, there are lots of variations on this theme.

Suicidal ideation: thinking about killing yourself. Passive suicidal ideation: thinking it would be good if you died, but not by your own action. Intent: wanting to kill yourself. Plan: having a way you want to do it. Means: you have access to the way you plan to do it.

Ideation itself is one indicator of depression. Having several of these would be an indicator of more immediate danger.
