IPA: /prɪˈmjuːnɪʃən/
KK: /prɪˈmjuːnɪʃən/
A type of immunity that occurs when a person has a low-level infection from a pathogen, which helps protect them from more severe infections by the same pathogen in the future.
The patient showed signs of premunition, as they had a mild infection that seemed to protect them from a more serious illness.
Premunition is formed from "pre-" (meaning before) and "munire" (meaning to fortify or defend). The word refers to a legal term that indicates a warning or precaution taken before an event, particularly in legal contexts.
Think of taking precautions 'before' ('pre-') to 'fortify' ('munire') yourself against something — that's what premunition means.
