Reporting Verbs Core Lecture

What Are Reporting Verbs?

In academic writing, reporting verbs (also known as referring verbs) are used to introduce and cite information from outside sources—such as books, journal articles, studies, and empirical reports. Instead of using conversational terms like says or talks about, reporting verbs allow researchers to integrate evidence while signaling their own stance toward the cited material.

Why Are They Crucial in Academic Writing?

Active & Passive Voice Core Lecture

Active Voice vs. Passive Voice

Passive Voice Structure & Agent

The passive voice is formed using a combination of the verb "to be" (in the appropriate tense) and the past participle of the main verb. The general structure is:

Subject + form of "to be" + past participle (+ optional "by" phrase)

The agent (the person or thing performing the action) is either omitted or included using "by" (e.g., The experiment was conducted (by the researchers).).

Purpose of Using Passive Voice in Academic Writing

In academic writing, the passive voice is used to maintain a formal, objective, and impersonal tone. Unlike the active voice, which emphasizes the performer of an action, the passive voice shifts focus to the action itself or its result. This is particularly useful when the initiator of the action is unknown or less relevant than the process or outcome.

Example: Instead of saying "Researchers conducted a study on bilingualism," academic writing often prefers "A study on bilingualism was conducted."
