Definition and Explanation of Adverbs of Information

Adverbs of information are a specific subset of adverbs that provide details about the source, certainty, reliability, or degree of information conveyed in a sentence. They help clarify how the speaker or writer obtained the information, their confidence level, or the nature of the evidence supporting the statement.

In terms of classification, adverbs of information fall under the broader category of adverbs of manner, degree, or certainty, but they are unique because they primarily relate to the epistemic status—how we know what we are talking about. These adverbs can appear in various positions within a sentence, such as at the beginning, middle, or end, depending on emphasis and style.

Functionally, they serve to:

Indicate the source of information (e.g., apparently, reportedly)
Express the speaker’s certainty or doubt (e.g., certainly, probably)
Show the evidence or basis for the statement (e.g., according to, evidently)
Convey the degree of confidence (e.g., possibly, likely)

In different contexts—formal, informal, academic, or conversational—adverbs of information help the speaker or writer position their statements in terms of reliability and source credibility. They are especially useful in journalism, research, academic writing, and reporting, where source attribution and certainty are critical.

Structural Breakdown and Patterns of Use

Adverbs of information typically follow certain structural patterns, though their placement can vary based on emphasis and sentence structure. Here are common patterns:

1. Adverb at the Beginning of the Sentence

This placement often emphasizes the source or certainty of the information.

Apparently, the meeting was canceled unexpectedly.
Reportedly, the company is planning to expand.
According to witnesses, the accident happened late at night.

2. Adverb in the Middle of the Sentence

This position often emphasizes the adverb without overshadowing the main message.

The suspect is probably involved in the crime.
She certainly knew about the problem.
The results are evidently inconclusive.

3. Adverb at the End of the Sentence

This placement can add a conclusive or summarizing tone, often emphasizing certainty.

He is guilty, apparently.
The project was successful, probably.
She will come, likely.

4. Adverb as Part of a Prepositional Phrase

Some adverbs of information function as part of a prepositional phrase, providing source or evidence.

According to the report, sales have increased.
Based on her statement, the decision was final. In view of recent findings, we should reconsider our approach.

Categories and Types of Adverbs of Information

Rules for Proper Use of Adverbs of Information

Understanding the correct application of adverbs of information is crucial for clarity and grammatical accuracy. Here are essential rules and guidelines:
