What does digest mean?
To digest is fundamentally to break something down so that it can be absorbed. In its original and most literal sense, it describes what the stomach and intestines do to food: reducing it chemically and mechanically into nutrients the body can use. By natural extension, English speakers use digest figuratively for the mind's equivalent process — taking in news, arguments, or complex ideas and gradually absorbing their meaning. As a noun, a digest is a condensed version of longer material: a summary or collection of key points, a sense preserved in titles such as Reader's Digest. The word derives from Latin digerere, 'to separate, divide, distribute', via Old French, and shares a root with gesture, suggest, and prestige. It is standard in both British and American English across registers, though the figurative sense leans slightly formal. A useful quirk of pronunciation marks its two roles: the verb stresses the final syllable while the noun stresses the first.
To break down food in the digestive tract so that it can be absorbed by the body; to process information or experience mentally; to treat a substance chemically in order to decompose it.
"She paused over the article, giving herself time to digest its argument."
The verb is stressed on the second syllable (/daɪˈdʒɛst/).
A summary or systematic condensation of written material; a publication consisting of such summaries.
"He skimmed the weekly digest to catch up on industry news."
The noun is stressed on the first syllable (/ˈdaɪdʒɛst/).
Standard plural for the noun sense referring to summaries or publications.
"The library subscribes to several legal digests."
The same word that describes your stomach breaking down dinner also means your brain breaking down a difficult idea — because to the ancient Romans, thinking really was a kind of internal digestion.

Etymology of digest
Digest comes from Latin digerere, meaning 'to separate, divide, or distribute', formed from dis- ('apart') and gerere ('to carry'). The word passed into Middle English through Old French digestier in the late medieval period, initially retaining the Latin sense of dividing or arranging matter before settling into its modern physiological meaning. Its Latin root also produced cognates such as suggest (literally 'to carry up from below'), gesture, and prestige, all involving the idea of carrying or conveying. The noun sense of 'a summary' preserves the older idea of matter sorted and arranged into order.

How digest is actually used
As a verb it is stressed on the second syllable (di-GEST), while as a noun it is stressed on the first (DI-gest) — a stress shift common in English two-syllable noun/verb pairs. The mental sense ('to take in information') often appears in progressive forms ('I'm still digesting that') and carries a neutral-to-formal register. The chemical-processing sense is largely confined to technical and laboratory contexts.
