What does itemized mean?
Itemized describes something that has been separated into individually listed parts, such as an expense report, invoice, budget, or set of proposed actions. The word emphasizes clarity and granularity: rather than presenting a total or general category, an itemized account shows what each component contributes. It is especially common in financial, administrative, and legal contexts, where detailed records help readers verify costs or understand decisions. As a verb, "itemized" means that someone has performed this process of listing entries separately. The term is most typical in North American English, while British English generally prefers "itemise." It is useful whenever precision and accountability matter, whether describing a household budget, a customer receipt, or the reasons behind a policy change.
Arranged or presented as separate, individually listed entries.
"She asked for an itemized statement of the charges."
Common in financial and administrative contexts.
To list the individual components or details of something separately.
"The auditor itemized the discrepancies before presenting them."
The usual form is the simple past tense or past participle; the base form is "itemize."
An itemized list turns a single amount or category into a transparent record of every component, making it easier to check, compare, and understand.
