The language of literature reviews

Expression in a literature review should be informative and evaluative. Apart from incorporating reporting verbs, you will need to use evaluative and cautious language.

Reporting verbs

A key language feature of a literature review is the use of reporting verbs. These types of verbs describe and report on the literature under review. They report on:

  • aims: investigates, examines, looks at
  • results: shows, suggests, reveals
  • opinions: states, believes, argues

The choice of reporting verb(s) indicates your perspectives and attitudes towards the research under review. That is the reporting verbs chosen show whether you are neutral, negative or positive about the research.

The sentence pattern of placing reporting verbs is: [reporting verb] + either/both [object] / [complement].

Evaluative and cautious language

You can show your perspective on the literature under review by using evaluative language. Evaluative language can indicate whether you’re positive or negative towards the claims in the literature, whether you agree or disagree with the claims presented.

Cautious language is careful not to express absolute certainty where there may be the possibility of uncertainty.

Evaluative language can be:

  • positive: e.g. expressions like “effective,” “necessary,” “significant” or “crucial”
  • negative: e.g. “questionable,” unclear,” “inconclusive” or insignificant.


Positive evaluation: Wright’s (2022) argument about the link between parental numeracy and that of their children is conclusively borne out in the interviews.

Negative evaluation: Whether the statistical results support Torney and Wittings’ (2021) hypothesis is debatable.

Another way to express certainty or hesitancy is to use boosters and hedges.

  • boosters are words or phrases that express confidence or certainty
  • hedges convey a qualified uncertainty in the claims made in the literature.
