Ways to tell them apart:

etymology
  • Which introduces non-restrictive clauses, often separated by commas, providing extra information that can be omitted without changing the main meaning of the sentence.
  • That introduces restrictive clauses, providing essential information about the noun it follows, and is not separated by commas.
  • Remember: if the sentence still makes sense after removing the clause, use which; if not, use that.
  • Use which when you want to add an interesting detail or additional description that isn't crucial to the main point.
  • Use that when the clause is defining or specifying something essential to the meaning of the sentence.
