I did not understand when 'that' and 'which' are interchangeable and when not. Is there any article about the usage of them?

Hello Ebi Soleymani,

This is a question which relates to relative clauses. There are two kinds: restrictive (also called defining) and non-restrictive (non-defining).

In non-restrictive relative clauses you cannot use 'that'.

In restrictive relative clauses it is possible to replace 'who' or 'which' with 'that' with no change in meaning.

You can read more about these structures by using the links above.

☆ Would you like to own any of Dyson's products?
- Yes, I'd like to own one of Dyson's products in the video. I think the fan is amazing since there are no rotating blades, the air multiplier must be more consistent and steady and the breeze from the fan doesn't buffet us with short gusts of air like we use the domestic fan.
By the way, Do you know how much the Dayson Bladeless fan cost?
