Cytolytic → It is formed from "cyto-" (from Greek "kytos", meaning cell) and "lytic" (from Greek "lytikos", meaning capable of loosening or destroying). The word "cytolytic" refers to the capability of destroying or breaking down cells.
Think of 'cells' ('cyto-') being 'destroyed' ('lytic') — that's what cytolytic means.
