Question

Is a colon used before a list and a semicolon before elaborating?

Answer 1

Yes.

Explanation:

Colons are used to show the start of a list. If you have detailed items in the list, then you can use semi colons in between to separate them.

e.g I went to the shop and bought: several large, juicy tomatoes; a new top for my sister; a new book (by my favourite author); and lots of soft drinks for my party tomorrow.
