“Summary,” meaning “an abstract,” is a noun. It names a shortened account of the main ideas, events, or findings in a longer work.
The word comes from the Latin “summarium,” meaning an abstract or summary, derived from “summa,” meaning “highest point” or “total.” In English, “summary” can refer to the condensed text itself: “The report includes a one-page summary.” It can also describe something brief or concise when used as an adjective, as in “summary proceedings,” but that is a different grammatical use.
A common mix-up is confusing “summary” with “summarize.” “Summary” is the noun, while “summarize” is the verb meaning to produce or state a summary. “Summarization” is another noun for the process of creating one. A summary is also not the same as a review: a summary mainly presents the essential content, while a review usually adds evaluation or criticism. In academic writing, an abstract is a specialized type of summary that commonly states a paper’s purpose, methods, results, and conclusions.
