Conjunctions Function as Preposition, Adverb, or Adjective

Introduction to Conjunctions

Before we delve  into how conjunctions can function as prepositions, adverbs, or adjectives, we should have a clear understanding of what conjunctions are. Literally, conjunction means to ‘join’ or ‘connect’. In grammar,  conjunction is a word that connects words, phrases, clauses, or sentences. Examples of commonly used conjunctions are: ‘and’, ‘but’, ‘or’,’so’, ‘because’, ‘although’, ‘yet’, ‘unless’, and ‘while’. After having a basic understanding of what conjunctions are, let’s explore how conjunctions can also function as other parts of speech, such as prepositions, adverbs, or adjectives.

Conjunctions as Adverbs

Adverbs modify verbs, adjectives, or other adverbs. They provide further information about an action, or about the condition or quality of what is being described. In certain cases, words that are commonly used as conjunctions can also be used as adverbs.

Lets take an e.g of the word ‘after’. When it acts as a conjunction, it connects two clauses, as in:

“I went to the grocery store after I finished my work.”

However, ‘after’ can also  function as an adverb, can be seen in this sentence:

“He came after.”

Important Points About Conjunctions as Adverbs

  1. Position: These words, when acting as adverbs, tend to be located at the end of the clause or sentence.
  2. Modification: As adverbs, they will modify the main verb of the sentence.

Conjunctions as Prepositions

Prepositions link nouns, pronouns, and phrases to other words in a sentence to depict relationships, such as location, direction, or time. Some conjunctions can play the role of a preposition when used in a suitable context.

Take the word ‘before’ as an example. When used as a conjunction, ‘before’ connects two clauses:

“I always brush my teeth before I go to bed.”

Contrarily, ‘before’ can also function as a preposition, as in this sentence:

“She arrived before me.”

Key Points About Conjunctions as Prepositions

    1. Function: These words, when acting as prepositions, usually show a relationship in terms of location or time.
    2. Placement: As prepositions, they usually precede a noun or a pronoun.

Conjunctions as Adjective

An adjective is a word used to modify a noun or a pronoun. It provides more information or describes the noun or pronoun. Conjunctive adverbs can occasionally function as adjectives. However, pure conjunctions don’t commonly function as adjectives.

Consider the word ‘just’. While generally used as an adverb, ‘just’ can occasionally function as a conjunction, as in the sentence:

“I just don’t understand why he did that.”

But ‘just’ can also be used as an adjective, as seen in this sentence:

“This is a just cause.”

Key Points About Conjunctions as Adjectives

        1. Role: These words, when serving as adjectives, modify a noun or pronoun and add more information to them.
        2. Placement: As adjectives, they usually precede the noun or pronoun they are modifying.


English grammar is not always categorical, as many words can play different roles depending on the context. This is true of conjunctions, that, in specific instances, can serve the function of adverbs, prepositions, or even adjectives. Understanding these alternate uses allows for a holistic apprehension of the flexibility and complexity of the English language. Through continuous practice and exposure in reading and writing, recognizing and employing these usages will become second nature in no time.
