It means wool forward but in this case it sounds more like a yarn over. I underlined the portion that would have the wf twice for a double yarn over. You would just wrap the yarn around the needle again. If it is a double yarn over, the next row usually gives directions for working it (either slipping one wrap off the needle or knitting one wrap and purling the other, for example). The row will increase 4sts across.
Can you give us a pattern link or tell us the name of the pattern and what it is? Could you quote the next few lines?
