Adverbs in English are traditionally defined as words that "describe verbs, adjectives, other adverbs, and sentences." Adverb phrases are formed by an adverb and any modifiers. Adverbs and adverb phrases perform six grammatical functions in the English language. The six functions are:
- Adverb phrase head
- Adjective phrase modifier
- Adverb phrase modifier
- Verb phrase modifier
The following sections discuss the six functions and include examples to illustrate use.

Adverbs first function as the heads of adverb phrases. The following italicized adverbs are examples of heads of adverb phrases:
- quite well
- incredibly quickly
Adverbs always function as the heads of adverb phrases.
Adjective Phrase Modifier
Adverbs and adverb phrases secondly function as adjective phrase modifiers. An adjective phrase modifier is a word or phrase that describes an adjective or adjective phrase. The following italicized adverbs are examples of adjective phrase modifiers:

Prepositional phrases can also function as adjective phrase modifiers.
Adverb Phrase Modifier
