IPA: /ˌɪn.dɪˈdʒɛs.tɪ.bəl/
KK: /ɪnˌdʒɛstɪˈbəl/
Something that is difficult or impossible for the body to break down and absorb after eating.
Some foods can be indigestible for certain people, causing discomfort.
Indigestible → It is formed from "in-" (meaning not) and "digestibilis" (from Latin "digestus", meaning to lead apart or to separate). The word "indigestible" means not able to be digested or broken down by the body.
Think of something that cannot be 'led apart' or 'broken down' — 'in-' means not, and 'digestible' relates to the ability to digest.
