Attachment
A deep emotional bond between people that makes them seek closeness and feel secure in each other's presence, especially during stress or uncertainty.

A lasting emotional connection between individuals, typically characterized by the desire for proximity, comfort-seeking during distress, and a sense of security in the other's presence. Originally studied in parent-child relationships, the concept extends to friendships, romantic partnerships, and other close bonds. Attachment patterns formed early in life often influence how people relate to others throughout adulthood.
What this means in real life
When a child falls and scrapes their knee, they run to a parent for comfort rather than a stranger—that instinct to seek out a specific person for reassurance is attachment in action.
What it isn’t
Attachment is not the same as dependency or clinginess. A securely attached person can function independently and explore the world; they simply know they have a safe base to return to when needed.
Commonly misused online
Social media often conflates attachment with obsession or unhealthy codependency, using 'attachment' to describe toxic relationships or possessive behavior—when healthy attachment actually involves trust and autonomy.
