Need help with a pattern please

Hi! If a pattern says: s1, k1, psso, does it mean that you should s1 k1 again, then pass the slipped stitch over? Or does it mean just " pass the slipped stitch over" snce it has already said s1, k1?? Thanks!!:muah:

You do not have to s1, k1 again.

Slip a stitch, knit a stitch, then pass the slipped st over the knitted stitch. Psso means pass slip(ped) stitch over.
