i have a very long list hence doing it individually will take too much time.
please help

Assuming each word is followed by a paragraph break (when you turn on
nonprinting symbols you see a backwards-P sign, as shown in

Open the Replace dialog. In the Find What box, type

^p

In the Replace With box, enter

,^&

Press the Replace All button.
