Ok I have read it, thanks

Please could you confirm that in the sentences above the error is that “what” is used as description clause ???

So the correct ones should be without “what”

thakns, again

Yes, you can simply leave out “what” in your sentences and they will be correct.[YSaerTTEW443543]

Hi alumno

Instead of using the word ‘what’, you could use ‘that’ in your sentences. However, the word ‘that’ is optional. So, as Torsten said, you could make your sentences correct simply by removing the word ‘what’:

“Where is the festival (that) you told me about?”
“The swe[color=blue]ater (that) I washed …”

Ok, thanks a lot for those good comments that make me think…

So… The sentences could be made correct by using ‘which’ instead of ‘that’… right?


Hi alumno

The sentences would be correct with the word ‘that’.

The word ‘which’ is more often used in a non-defining clause (and a non-defining clause would also be separated from the rest of the sentence with commas).

Example of a non-defining clause:

The Festival of Lights, which is held annually, starts today at 6 pm.

The clause “which is held annually” is “extra information” in the sentence.
