Morphology

chemical + imbalance

The phrase directly combines 'chemical' (relating to chemicals) with 'imbalance' (an unequal or disrupted balance), so a learner who knows both constituents can infer it refers to an abnormal balance of chemicals in the body or brain. Although the term is used in clinical contexts (e.g., mental health) which add nuance, the core meaning is compositional and cross-linguistically accessible.

Etymology

Chemical imbalance comes from a simple picture: imagine tiny chemicals in the brain like ingredients on a scale, and when the amounts are wrong you get an imbalance. That's why people use the phrase to talk about changes in brain chemistry that can cause 'mood' or 'mental health' problems.
