What does codependent mean?
Codependent describes a pattern of excessive emotional and psychological reliance on another person, most often a partner struggling with addiction, illness, or dysfunction. A codependent individual tends to organize their life around the other's needs — caretaking, rescuing, and enabling — while neglecting their own wellbeing, so much so that their sense of identity becomes bound up with being needed. The word functions chiefly as an adjective ('a codependent relationship') but also serves as a noun for a person exhibiting these traits. It emerged in twentieth-century American psychology, originally in the context of alcoholism treatment, and has since entered everyday speech, though it retains negative connotations. Crucially, it should not be confused with interdependent, which denotes a healthy, balanced mutual reliance. Recognizing codependent dynamics can be a first step toward setting healthier boundaries.
Relating to or characterized by excessive emotional or psychological reliance on a partner, especially one requiring support because of addiction or illness.
"She ended the codependent relationship after years of putting his recovery ahead of her own health."
Frequently applied to relationships rather than individuals.
A person who exhibits an unhealthy degree of emotional or psychological dependence on another, often acting as an enabler of that person's addictive or dysfunctional behavior.
"The counselor explained that the codependent often mistakes controlling behavior for love."
Used mainly in therapeutic contexts when referring to people identified as codependent; some consider labeling people this way reductive.
"Support groups offer resources not only for addicts but also for their partners, many of whom identify as codependents."
Codependent began as a clinical label for spouses of alcoholics — then escaped the therapist's office to become one of pop psychology's favorite diagnoses.

Etymology of codependent
Codependent combines the prefix 'co-', from Latin meaning 'together', with 'dependent', from Latin dependere, 'to hang down from' (de- 'down' plus pendere 'to hang'). The term arose in mid-twentieth-century American addiction-treatment literature, where it was applied to spouses and family members of alcoholics — sometimes styled 'co-alcoholic' before 'codependent' prevailed. Its Latin-root relatives include pendant and pendulum, both built on the same verb pendere.

How codependent is actually used
The word originates in psychology and addiction treatment but is now widely used informally, sometimes loosely for any clingy relationship. It carries strongly negative connotations; describing a healthy mutual reliance requires 'interdependent' instead.
Easily confused with codependent
Interdependence is a healthy, balanced mutual reliance, whereas codependence implies an unhealthy, imbalanced dependence often involving enabling or loss of self.
A dependent person relies on others for support generally, while a codependent person's identity and self-worth are excessively bound up in another person, often someone with an addiction or illness.
