Jenny Watson design

I have a pattern in the book and the lace pattern says
K1, yfwd,s1,k1,psso,k1,k2tog,yfwd,k1’repeat to end.

Does the yfwd mean just that or yarn over? :knitting:

In this pattern, the yfwd IS a yo. Some people think of a yo as bring the yarn to the front then work the next stitch or decrease.
