SLIPS BACK is an 8-letter term that can be defined as 'relapses'. It is used to describe a situation in which someone or something returns to a previous state or condition after making some progress. This could refer to a person's health, behavior, or even a process or system. For example, if someone has been making progress in their recovery from an illness, but then slips back into a worse state, they have 'slipped back'.
