IPA: /ɪnˈkɒntɪnənt/
KK: /ɪnˈkɒntɪnənt/
Not able to control bodily functions, especially urination or defecation; also refers to lacking self-control or restraint in behavior.
The elderly man was incontinent and needed assistance with his personal care.
Incontinent is formed from "in-" (meaning not) and "continere" (meaning to hold together or restrain). The word describes a state of not being able to hold or restrain bodily functions.
Think of 'not holding' ('in-') something together ('continere') — that's why incontinent means unable to control bodily functions.
