Vocabulary For History Essay


When taking the ACT essay section, students have 45 minutes to write a well-reasoned argumentative essay about a given prompt. The new ACT Essay prompts tend to be about “debate” topics — two sides of an issue are presented, with no obviously “right” side. Oftentimes, these subjects carry implications for broader issues such as freedom or morality. Test-takers are expected to convey some stance on the issue and support their argument with relevant facts and analysis.


In addition to some of the more obvious categories, like grammar and structure, students’ essays are also evaluated on their mastery of the English language. One way to demonstrate such mastery is through the correct usage of advanced vocabulary words. Below are 50 above-average vocabulary words sorted by the contexts in which they could most easily be worked into an ACT essay.


Context 1: Factual Support For ACT Essay

Context 3: Thesis and Argument

These words are appropriate for taking a stance on controversial topics, placing greater weight on one or the other end of the spectrum, usually touching on abstract concepts, and/or related to human nature or societal issues.


  • Autonomy – independence or self governance; the right to make decisions for oneself – N
  • Conundrum – a difficult problem with no easy solution – N

  • Disparity – a great difference between things – N
  • Divisive – causing disagreement or hostility between people – Adj.
  • Egalitarian – favoring social equality and equal rights – Adj.


Although it’s true that vocabulary is one of the lesser criteria by which students’ ACT essays are graded, the small boost it may give to a student’s score could be the difference between a good score and a great score. For those who are already confident in their ability to create and support a well-reasoned argument but still want to go the extra mile, having a few general-purpose, impressive-sounding vocabulary words up one’s sleeve is a great way to tack on even more points.

Every field has its distinctive vocabulary. The word "document," for example, evokes a quite-different expectation in the mind of one who does historical research vis à vis, say, a software architect. The following basic vocabulary is a sampling of many such terms defined in EE's glossary (pp. 819–30, all editions).

analysis: the process of examining evidence. For students of history, this typically involves (a) studying individual pieces of data for inherent clues, strengths, and weaknesses; (b) correlating details from different sources in search of patterns; and (c) determining whether the whole body of evidence amounts to more than the sum of the individual parts.

assertion: a claim or statement of “fact.”

assumption: a typically premature conclusion unsupported by evidence.

authored work:a new and original narrative; in historical research, typically a work created by someone who studies many records and the relevant works of many other authors, drawing from this study a synthesis of knowledge on the subject and a set of personal conclusions. In this sense, an "authored" work is not to be confused with a compiled work (q.v.)

best evidence:an original record or records of the best and highest quality that survives. At law and in history research, a derivative record (q.v.) is rarely considered sufficient for documentation when an original—or a derivative closer to the original form—exists.

bibliography: a list of sources relevant to the subject at hand, citing each source in full. An annotated bibliography is one that discusses the sources in addition to providing full citations. A bibliography typically does not cite individual manuscripts or documents; rather, it cites a collection or series in which the manuscript appears. Also see source list.

citation: the statement in which one identifies the source of an assertion. Common forms of citations are source list entries (bibliographic entries), reference notes (endnotes or footnotes), and document labels.

(to) cite: the act of identifying a source or sources that support an assertion—not to be confused with the words site (as in website) or sight (as in eyesight).

claim: an assertion for which no evidence is supplied or else the evidence is insufficient or not yet adjudged.

compiled work: an aggregation of data, historical "facts," abstracted records, and similar raw materials, presented without an effort to form historical conclusions of the type that characterize an authored work (q.v.)

conclusion: a decision. To be reliable, it must be based on well-reasoned and thoroughly documented evidence gleaned from sound and reasonably exhaustive research.

confirm: to test the accuracy of an assertion or conclusion by (a) consulting at least one other source that is both independently created and authoritative; and (b) finding agreement or compatibility between them.

correlate: to compare and contrast separate items in order to identify conflicts and agreements between them and to define patterns and relationships.

derivative record: material produced by copying an original record or manipulating its content. Abstracts, compendiums, compilations, databases, extracts, transcripts, and translations are all derivatives.

direct evidence: relevant information or assertions that state an answer to a specific research question—whether rightly or wrongly. See also indirect evidence.

document—noun: (legal context) any piece of writing submitted into evidence; (historical context), a piece of writing, usually official, that has evidentiary merit.

(to) document—verb: to supply reliable evidence in support of an assertion.

discursive note:a reference note, keyed to text, that discusses tangential matters related in some way to the narrative but not directly on topic.

document label: a citation (q.v.) of source placed upon or appended to a document.

endnote: a reference note (q.v.) that is placed at the end of an essay, chapter, book, or other piece of writing.

evidence: information or assertions that are relevant to the research problem. Common forms used in historical analysis include best evidence (q.v.), direct evidence (q.v.), indirect evidence (q.v.), and negative evidence (q.v.).

fact: a presumed reality—an event, circumstance, or other detail that is considered to have happened or to be true. In historical research, it is difficult to establish actual truths; therefore, the validity of any stated “fact” rests upon the quality of the evidence presented to support it.

factoid: a “fact” that is fictitious or unsubstantiated but repeatedly asserted to promote its acceptance.

folio: a large sheet of paper folded to make leaves or pages for a book—usually four pages or multiples of four.

independent source: an original source (q.v.); one that did not take its information from any other. Researchers try to verify information by finding other independent (original) sources that report the same.

indirect evidence:relevant information or assertions that do not explicitly address the research problem but can be coupled with other evidence to suggest an answer or build a case to resolve the problem.

inference: a “fact” deduced from information that implies something it does not state outright.

information: a statement offered by a source. Information exists in two basic weights, primary information (q.v.) and secondary information (q.v.).

manuscript: a piece of writing in its native, unpublished state. Derived from the Latin meaning written by hand, the term is also applied in modern times to typed but unpublished copies.

master source list: a term used by some relational databases to refer to a “pick list” or “master list” of sources in abbreviated form.

monographs: a scholarly piece of writing on a specific (and often narrow) subject, typically book-length.

negative evidence:the absence of a situation that should happen under a given set of circumstances.

original record: a source that is still in its first recorded or uttered form. The term is also more loosely applied to image copies of an original record when produced by an authoritative or reliable agency—as with microfilm or digital copies produced to preserve the originals or to provide wider access to them.

primary information: a statement made or details provided by someone with firsthand knowledge of the facts he or she asserted. See also secondary information.

proof: a conclusion backed by thorough research, sound analysis, and reliable evidence. It may be expressed as a citation (in extremely simple cases), a proof summary (a set of citations), or a proof argument (an essay that develops the evidence, both pro and con, with documentation).

reference note: a citation (q.v.) or comment placed at the bottom of a page or at the end of a piece of writing and keyed to a particular statement in the text; its purpose is to identify and/or discuss the source of the specific statement made in the text.

record: an authoritative document created by a civil or religious agency. It may be a standalone document (loose sheets, unbound) or it may be recorded in an official register. Within historical research, the term a record typically refers to the entire document, not to individual assertions extracted from the document and stripped of the context that can be gleaned by studying the whole.

repository: an archive, government office, library, or other facility where research materials are held; in the case of privately held material, it is typically a personal residence. In a virtual sense, the internet is a repository, while individual websites are publications.

secondary information: Details provided by someone with only secondhand (hearsay) knowledge of the facts. The term secondary is also generically used for tertiary (thirdhand) and other levels of knowledge even further removed from the original source.

source: an artifact, book, document, film, person, recording, website, etc., from which information is obtained. A source is broadly classified as either an original record (q.v.) a derivative record  (q.v.), or an authored work (q.v.), depending upon its physical form.

source list: a bibliography or list of sources used for an essay or in a research project; typically but not always arranged in alphabetical order.

source list entry: an individual citation within a source list (q.v.).

speculation: an opinion unsupported by evidence.

subsequent (or short) reference note: an abridged identification of a source that is used to conserve space, once a source has been cited in full in the first reference note (q.v.)

verification: confirming the accuracy of an assertion by consulting other authoritative and independent sources; the term may be applied to the process of searching for that independent evidence or the act of finding that independent evidence.

working source list: a list of sources consulted or to be consulted in a research project. A working source list typically contains descriptive or analytical details that will not be published in a final bibliography, unless the final work presents an annotated bibliography. A working source list may also contain references that will not be considered valid or appropriate to the final research product.
