Abbreviation interpretation, please

hi, all…

the saga of my first sweater continues. i’m most of the way through the back and this morning, i came upon this:

[B]Dec Row (RS):[/B] K2, KSP, k to last 4 sts, SSK, k2 – 71(77-85-93-99-109) sts.

what the heck is KSP? i realize its some sort of a decrease to match the SSK at the end of the row, but i can’t seem to figue this out and this particular is not listed on any abbreviation list i’ve been able to lay hands on. could this be a typo in the pattern? could it be SKP?

any thoughts anyone has would be appreciated.

best,
historienne

From the Berroco website…

[B]KSP:[/B] K1, then sl st back to LH needle, lift 2nd st on LH needle back over returned st and replace returned st on RH needle (1 st dec’d).
