IPA: /ˌhaɪpəˈkɒndriə/
KK: /haɪpəˈkɒndriə/
A condition where a person is excessively worried about having a serious illness, even when there is no medical evidence to support this belief.
Her hypochondria made her visit the doctor frequently, even for minor aches and pains.
Hypochondria is formed from "hypo-" (meaning under or below) and "chondros" (meaning cartilage or rib). The term originally referred to the area beneath the ribs, which was thought to be the seat of various ailments, hence the association with excessive worry about health.
Think of 'hypo-' meaning 'under' and 'chondros' referring to the 'ribs' — this helps you remember that hypochondria involves worrying excessively about health, particularly related to the area beneath the ribs.
