IPA: /ˌɪn.dʒʊˈreɪ.ʃən/
KK: /ɪnˈdʊəreɪʃən/
The process or condition of becoming hard, especially in relation to soft tissues or organs due to inflammation or other factors.
The doctor noted the induration of the skin during the examination.
Induration is formed from "in-" (meaning not) and "durare" (meaning to harden). The word describes a state of being not soft, indicating a hardening or firmness of tissue.
Think of something that is 'not soft' — 'in-' means not, and 'durare' means to harden. This helps you remember that induration refers to a hardening.
