Etymology: "Itemiser" is a plain formation: the verb "itemise" with the agent suffix "-er" added, giving a noun for something or someone that itemises. "Itemise" itself comes from "item," the Latin word meaning "likewise" or "also," which was used in medieval English lists and inventories to introduce each further entry, so an itemised list is literally a list of "also" entries, one added after another. The suffix does the work here. "-er" attaches to a verb to name the doer or the device, as in "printer" or "sorter," and that is how "itemiser" describes either a person who breaks a collection into listed parts or a piece of software or mechanism that does so automatically. The word is recent and technical in character, closer to a practical label than to a term with a long literary past.

Synonyms: enumerator, list-maker, cataloguer, compiler, register
