Sure, I can help you with that! Here's how you can create a bilingual document with two side-by-side columns in Microsoft Word:

1. Open a new Word document and go to the "Page Layout" tab in the ribbon.
2. Click on "Columns" and select "Two" to create two columns on the page.
3. Type or paste the text for one language in the left column and the text for the other language in the right column.
4. To make sure the columns stay side-by-side on each page, go to the "Page Setup" dialog box (click on the small arrow in the bottom right corner of the "Page Setup" section in the "Page Layout" tab).
5. In the "Margins" tab, select "Multiple pages" under "Pages" and then select "Mirror margins" under "Margins."
6. Click "OK" to apply the changes.

Now, your document should have two columns side-by-side, one for each language, and the margins should be set up so that the columns stay side-by-side on each page. You can continue typing or pasting text into each column as needed, and the document will automatically flow from one column to the other.

If you need to adjust the width of the columns, you can do so by dragging the vertical line between the columns to the left or right. You can also adjust the spacing between the columns by going to the "Columns" dialog box and selecting "More columns" to access additional options.
