The term hydrolysis means "breaking-up" (lysis) "due to water" (hydro).

Many reactions are of the form X-Y + H2O -> X-H + HO-Y, and these reactions can be driven by removing water.

Hydrolysis reactions are usually multi-step processes with sequences of protonation followed by attack of HO- or H2O, or attack of HO- followed by protonation.
