Concept clusters

Root unlock

pend (to hang). The Latin root 'pendere' paints a vivid picture of something hanging from a support. When we are dependent, we are figuratively 'hanging down' from someone or something else. In an 'interdependent' relationship, two entities are 'hanging together' in a balanced way, while 'codependent' suggests a more tangled, often problematic mutual hanging that is difficult to separate. Unlocks: interdependent, codependent
