  • Because: This word is a conjunction, typically followed by a subject and a verb. It is used to introduce a reason or cause for an action or event. For example: "He fell because he wasn't paying attention".
  • Because of: This phrase is a preposition, followed by a noun, noun phrase, gerund, gerund phrase, object pronoun, possessive adjective, or wh- clause. It is also used to introduce a reason or cause for an action or event. For example: "We went to the pub because of our hunger".

  • Use "because" when you need to modify a clause, as it is a conjunction.
  • Use "because of" when you need to modify a noun or noun phrase, as it is a preposition.
