Confusing Words

because vs since / given that

These three connectives all introduce a reason or cause, but they carry different implications and suit different contexts.

  • because — Because is the most direct and explicit: it states a cause in a straightforward, unambiguous way and is appropriate in most formal and informal writing. Use because when you want to clearly explain why something is the case.
  • since — Since can be used to introduce a reason, but it also means ‘from a point in time’ and can therefore be ambiguous in sentences where both meanings are possible. In careful formal writing, since as a causal connective works best when there is no risk of temporal confusion.
  • given that — Given that is used to introduce a premise or assumption that is already accepted or established, on the basis of which a conclusion follows. It is particularly precise in academic and legal writing, where the starting point needs to be clearly acknowledged.
  • in light of — in light of' means considering this evidence, fact or situation; use it when that exact meaning is needed, rather than choosing a nearby word that only sounds similar.

Memory rule: A practical guide: use because for a straightforward, direct cause; use since carefully in contexts where the temporal meaning cannot be confused with the causal one; use given that when the reason is already accepted as an established fact or premise.
