Cytological → It is formed from "cyto-" (from Greek "kytos", meaning cell) and "-logical" (from Greek "logia", meaning study or science). The word "cytological" refers to the study or science of cells.
Think of 'cyto-' meaning 'cell' and '-logical' meaning 'study' — so cytological is all about the study of cells.
