If you use the same block of text in several Word documents and you frequently update the text, you can use the Linked Text feature so that when you change the text in the original document those changes will be automatically applied to all other linked documents.

Open the original document that contains the text.

Copy the text to the clipboard.

Open or create the other document(s)

Position your cursor where you want the text to appear.

On the office ribbon click the paste icon and then select “Paste Special”

In the Paste Special window that opens select Paste Link > Formatted Text (RTF). Then click the OK button, and your text will appear.

Save the document after you have pasted the text.

Repeat this process for each document you want to link to the original text.

Now, whenever you edit the text in the original document, the changes will be reflected in the other linked document(s)
