Difference between Preposition and Conjunction

In English grammar, prepositions and conjunctions are two key components of speech that are frequently used to connect words, phrases, and clauses.

Understanding the difference between prepositions and Conjunctions is critical for writing clear and effective sentences in English.

Difference between Preposition and Conjunction #Meaning


A preposition is a word placed before a noun or noun equivalent to show its relationship to another word in the sentence.

In the sentence “Lisa placed her hand on the desk,” the word on shows the relationship between the hand and the desk. Omitting the word on makes no sense.

The hand may be on the table, under the table, or above the table. The relation between hand and table is not known until some preposition is inserted. The word on is, therefore, a preposition.

Conjunctions are words used to join sentences, phrases or clauses. 

Conjunctions that join words or phrases

  • I need a book and a pen.
  • I need a book or a pen.
  • I need not a book but a pen.
  • I need a book as well as a pen of good quality.

Difference between Preposition and Conjunction #Types


There are 6 types of Prepositions

  1. Simple Prepositions
  2. Double Prepositions
  3. Compound Prepositions
  4. Participle Prepositions
  5. Phrase Prepositions
  6. Disguised Prepositions

Simple prepositions

Simple Prepositions are at, after, by, for, from, in, of, on, out, over, through, till, up, under, with, off, till, over, etc.

  • I put my keys on the table.
  • The plane flew over the mountains.
  • I will cook dinner with my mom tonight.
  • Please turn off the lights when you leave the room.
  • He will arrive at 10 a.m.

Double prepositions

When a single preposition is not sufficient to express the sense, two simple prepositions are combined to express the sense completely.

Some Double Prepositions are into, from among, from within, from behind, over against, out of, etc.

  • He was chosen from among a group of talented musicians.
  • The cat emerged from within the bushes.
  • The thief sneaked away from behind the parked car.
  • The car was parked over against the wall.
  • The bird flew out of the tree and into the sky.

Compound prepositions

Compound prepositions are formed by combining two or more words to form a new proposition. Compound prepositions are usually formed by prefixing a preposition with a noun, an adjective, or an adverb.

Some examples of Compound prepositions are as follows:

  • across (= on + cross),
  • amidst (= on + middle),
  • behind ( = by + hind),
  • about (= on + by + out),
  • above (= on + by + up),
  • before (= by + fore)
  • beneath (= by + neath),
  • between (=by + twain),
  • beyond (= by + yonder),
  • but (= by + out, except)

Participial prepositions

Some present or past participles such as considering, concerning, regarding, pending, notwithstanding, etc. are used as prepositions. These words are known as Participle Prepositions.

  • Notwithstanding her boss’s criticism, the employee submitted her report.
  • Regarding this matter, I cannot provide any additional information.
  • The stream flows past the meadow.
  • Barring any unforeseen circumstances, the plane will take off on time.
  • Concerning her artwork, critics have mixed opinions.

Phrase prepositions or Prepositional phrases

When a phrase begins and ends with a Preposition (of, at. by. with, from, over etc.) it is called a Prepositional Phrase.

Some common Phrase Prepositions are – On the eve of, In consequence of, In the place of, In company with, At enmity with, In keeping with, In prospect of, Because of, By force of, In pursuit of, With an eye to, By the side of, By means of, etc.

Disguised prepositions

When the prepositions ‘on‘ and ‘of‘ are changed, into ‘a‘ and ‘o‘ respectively they are called Disguised prepositions; as

This fair is held once a year” – “A” is used here as a shortened form of “on,” indicating that the fair is held on a yearly basis.

“It’s ten o’clock now” – “O” is used here as a shortened form of “of,” indicating that the time is ten hours of the clock.

Conjunctions that join the clauses are subdivided into two main classes –
