Online English Course: English Grammar: Basic Parts of Speech: Lesson 8: Conjunctions



A conjunction is a word or words used to show the relationship between one notion and another notion. There are two main types of conjunction: the coordinative conjunction, which joins phrases of equal importance and rank, and the subordinative conjunction, which joins a phrase with another phrase that is dependant on it.

Coordinative Conjunctions

A coordinative conjunction joins two sentences together that do not rely on each other for meaning. We can split the co-ordinative conjunctions into four smaller groups: the cumulative, the alternative, the adversative, and the illative.


A cumulative conjunction is used to add one thought to another. Examples of cumulative conjunctions include

  • and
  • both…and
  • not only
  • but also
  • as well as takes singular verb


Used to indicate a choice between one notion and another. For example:

  • or
  • either…or
  • else
  • otherwise
  • neither…nor


Used to contrast one notion and another.

  • but
  • yet
  • however
  • nonetheless
  • despite
  • still


These show that one notion is implied, inferred or proved by another.

  • then
  • thus
  • therefore
  • so
  • for

Subordinating conjunctions

Subordinating conjunctions express relationships of time, manner, cause or reason, comparison, condition, or purpose. They are used to introduce subordinate clauses that are not complete
