How to use "as a result of"

What Does "as a result of" Mean?

  • Grammatical function: It is a complex preposition used to express a causal relationship. It identifies the specific cause or reason that led to a particular effect or consequence.
  • Typical sentence position: It is highly versatile and can appear in the initial (starting a sentence), medial (middle of a clause), or final position.
  • Register: It is primarily formal to neutral. It is a staple of academic writing, journalism, legal documents, and professional correspondence.

How to Use It

  • Syntactic patterns: As a prepositional phrase, it must be followed by a noun phrase or a gerund (the "cause"). It cannot be followed immediately by a full clause (subject + verb).
  • Punctuation rules: When placed at the beginning of a sentence, the entire introductory phrase is usually followed by a comma. When used in the middle or end of a sentence, commas are generally not required unless the phrase is parenthetical.
  • Grammatical flexibility: It can be moved easily within a sentence to change emphasis. It can also be modified by adverbs (e.g., "largely as a result of").
  • What sounds unnatural or incorrect: Using it as a standalone transition word (e.g., "As a result of, the project failed") is a major grammatical error. It requires an object to complete the prepositional phrase.
