Are the books tied up?

[Yourjones]

Hi,

Can I say "The books are tied up with plastic string. If you want to untie them, you need to pull the end of string because it is a the slip knot"?

Doubts lie in:
tied up, string, the end of the string

Thanks.

I'd use "tied together". Note that you have a double article before "slip knot" - you used "a the". The indefinite article is correct.

Add 'the' after 'end of' in your sentence as well as in your doubts list.

I​ missed that.

They're tied together with a ribbon.

And you could say the ends of the string.

No 'a' before 'plastic'?

No.
