How to copy a translation from a word file into a trados project?

Hello everyone

I have a very simple question, yet it seems very difficult to get a sensible answer to it in any knowledge base, which is why I'm asking directly now:

I have an open Trados project with no translations in the target language column. Now I want to fill that column with an existing translation from a word file or simply from the clipboard. What is the simplest way to achieve that?

Thanks in advance for your help.
