Any of an adverb, an adverb phrase or an adverb clause can describe a verb.
adverb clause
"Big" is an adjective. It is used to describe the size or extent of something, such as in the phrase "a big house." It does not function as a verb.
For something to be a clause, it must contain a subject and a verb. An appositive phrase does contain a verb. It's a phrase, associated with a noun, which provides more information about that noun (note that in this sentence, "associated with a noun" is an appositive phrase).Another example of a sentence with an appositive phrase is this:"Johnny, my neighbor, planted a tree."A similar sentence with an adjective clause is this:"Johnny, who lives next door to me, planted a tree."
adverbial clause
No, describe is a verb. The adjective form is describable.
adverb clause
"Lost in thought" is a phrase or a group of words that acts as an adjective to describe someone who is absorbed in their thoughts. It is not a clause because it does not have a subject and a verb to form a complete sentence.
They both describe a part of the larger sentence. However, a phrase does NOT have a verb it is. A Clause has a VERB in it. e.g. King Charles(III) , who is King of England ; contains a clause , because it contains the verb 'is' . King Charles(III) , the King of England ; is a phrase. No verb 'is'!!!!
An adverbial phrase. A word, phrase, or clause of a sentence has the aspect of an adverb if it modifies a verb. By the same token, a word, phrase, or clause of a sentence that modifies a noun would be an adjective, adjectivial phrase or adjectivial clause.
"Big" is an adjective. It is used to describe the size or extent of something, such as in the phrase "a big house." It does not function as a verb.
An adjective clause is the group of words that contain the subject and the verb acting as an adjective. An adverb clause answers questions like how, when and where.
"We had fun" is a clause because it contains a subject ("we") and a verb ("had"). A phrase, on the other hand, does not contain both a subject and a verb.
For something to be a clause, it must contain a subject and a verb. An appositive phrase does contain a verb. It's a phrase, associated with a noun, which provides more information about that noun (note that in this sentence, "associated with a noun" is an appositive phrase).Another example of a sentence with an appositive phrase is this:"Johnny, my neighbor, planted a tree."A similar sentence with an adjective clause is this:"Johnny, who lives next door to me, planted a tree."
adverbial clause
a clause has a subject and a verb and may or may not complete a though (depended on a subordinate clause or independent). A prepositional phrase has a preposition and the object of the preposition
An infinitive phrase is a group of words that starts with an infinitive (to + verb) and includes any objects or modifiers related to the verb. An adjectival clause (a type of relative clause) is a group of words that functions as an adjective and provides more information about a noun or pronoun in the sentence.
An adjective can only modify a noun, pronoun, or noun phrase. It cannot modify a verb, adverb, adjective, or other part of speech...or it would not be acting as an adjective.
