Yrn

is that the same as yarn over? I’m looking at the Star Stich in the Harmony Guide to Knitting techniques. The instructions say “p3tog leaving stiches on the needle, yrn, then purl the smae 3 stiches tog again.” :?? It’s a real pretty looking texture in the book too. Anyone ever done this?

I googled yrn and this is what came up.

Thanks.
