Adverbial vs. Adjunct: What's the Difference?

By Harlon Moss & Aimie Carlson || Updated on May 28, 2024
Adverbial modifies verbs, adjectives, or other adverbs, describing manner, place, time, or degree. Adjunct is a type of adverbial that provides additional, non-essential information to a sentence.

Key Differences

Adverbial refers to a word or phrase that modifies verbs, adjectives, or other adverbs, describing how, when, where, or to what extent an action occurs. For example, in the sentence "She sings beautifully," the word "beautifully" is an adverbial modifying the verb "sings." Adjunct, on the other hand, is a type of adverbial that adds extra, non-essential information to a sentence. This additional information can often be omitted without altering the fundamental meaning of the sentence. For instance, in "She sings beautifully in the morning," the phrase "in the morning" is an adjunct.
While all adjuncts are adverbials, not all adverbials are adjuncts. Adverbials can also be complements, which are necessary to complete the meaning of the verb. For example, in "She put the book on the table," "on the table" is an adverbial complement necessary for the sentence to make sense.
Adjuncts are typically more flexible in their placement within the sentence and can be moved around or omitted without impacting the sentence's core meaning. They enrich the sentence by providing additional details such as time, place, manner, reason, or condition, enhancing the overall context.
Adverbials modify verbs and other elements to give more detail about actions, while adjuncts specifically provide optional, extra information that enhances but is not critical to the sentence's meaning.
