An abbreviation for pass slipped stitch over. This technique is used to decrease the number of stitches on the needle by one, creating a visible left-leaning slant in the knitted fabric. The knitter slips a stitch unworked, knits the next stitch, and then uses the left needle to lift the unworked stitch over the knitted one and off the right needle.
The lace chart says to knit two together, yarn over, then slip one, knit one, psso.
Do not mix it up with
- SSK: Both decrease by one stitch and lean left, but ssk involves knitting two stitches together through the back loop, while psso lifts an unworked stitch over a worked one.
