indigestion

The word 'indigestion' is a direct borrowing from Late Latin indigestio, which itself was formed from the Latin prefix in- (meaning "not") and the noun digestio (meaning "digestion, arrangement"). The core Latin verb digerere meant "to separate, dissolve, or distribute," a concept applied literally to the body's process of breaking down food. Over time, the term evolved in medical and common English usage to specifically denote the condition resulting from the failure of this process. Its secondary, figurative meaning of a failure to mentally "digest" or comprehend information logically extends from this original physiological concept.

Structure: in (not) + digest (break down) + ion (noun suffix) - in: Latin origin, a prefix meaning "not" or "without". - digest: Latin origin, from digerere meaning "to separate, divide, dissolve". It functions as the core verb meaning "to break down food". - ion: Latin origin, a suffix forming nouns denoting an action, process, or its result.
