What does undigested mean?
Undigested is an adjective with both a literal and a figurative range. Literally, it describes food or other material that has not yet been broken down by the digestive system. Figuratively, it refers to information, ideas, experiences, or emotions that have not been fully processed, understood, accepted, or assimilated. The figurative use often suggests incompleteness rather than any suggestion of being spoiled or worthless: an undigested report may contain valuable material that simply requires more thought. In everyday discussion, the expression is especially useful for describing a crowded collection of facts or a difficult experience that cannot be understood immediately. It can also describe emotions that remain unsettled. Across British and American English, undigested is more often encountered in figurative writing and conversation than in formal scientific or medical terminology.

Where does undigested come from?
The word was formed in English in the early 17th century from the prefix un- and the past participle digested. Digest comes ultimately from Latin digerere, a compound of de-, meaning apart, and gerere, meaning to carry or bear; the verb later came to mean to assimilate food. Related English forms include digestion, digestible, and indigestible.
