Grammar Rules: That versus Which

grammar rule, english grammar, grammar check, grammar help
"That" is used when essential information follows.

"Which" is used when non-essential information.

The rules are a little more complicated, but those are the basics.



  • Funding is used to help companies that have been approved by the government.
  • The file cabinets hold IRS returns that have been filed.


  • Non-fiction books are on the back shelf, which is a bit of a walk from here.
  • Retrievers are touted as being the best dogs around children, which is better for your needs.

By the way, "Who" refers to people. "That" and "which" refer to things, so don't use "that" when referring to people.

English Grammar Rules: Good or Well?

I’ll never forget my 7th-grade Language Arts teacher telling us that we “could never do anything good.”

Yes, it seems a bit harsh, but it’s true, and it’s the method she used to help us understand when to use WELL and when to use GOOD.

WELL – an adverb, which describes HOW something is done.

  • Shelley rides really well. (Describes how she rides.)
  • Chad paints so well that his teacher is recommending him for the scholarship. (Describes how he paints.)
  • Would you say she writes well? (Describes how she writes.)

GOOD – an adjective, which describes a NOUN (person, place, thing, idea, or concept).

  • The lasagna is so good. (Describes the lasagna.)
  • The writer is better than good; he’s fabulous! (Describes the writer.)
  • It was a good website that had up-to-date information. (Describes the website.)


  • It was good plan, and it was carried out well. (Good describes the plan, and well describes how it was carried out.)
  • She’s a good architect, and her work is well received. (Good describes the architect, and well describes how her work is received.) Teaching & Technology articles
