Itemise → It is formed from "item" (from Latin *item*, meaning also or likewise) and "-ise" (a suffix used to form verbs). The word "itemise" means to list or specify items individually.
Think of listing things 'likewise' ('item') and turning that into a verb with '-ise' — that's how you remember that 'itemise' means to list items.
