Yarn Forward before a Purl Stitch; Knit Stitch

My pattern states the following:
Yarn forward, P1 - I have the yarn forward to make all Purl sts so why is YF before the P1?
Yarn forward K1 - Does this mean to make a Yarn Over?
Yarn Forward SKP - Does this mean to make a Yarn Over?
Any help you can give me will be appreciated

What are you making, what pattern? Is it lacy?

It probably does mean to make a yo.

Is the YF before a Knit stitch, before a Purl Stitch and before an SKP a YO?

I merged your two topics because you’re asking the same thing. No need to post twice.

I’m not sure what you’re asking. A YF (aka YO) can be before any stitch.

If it’s before a knit stitch you bring the yarn forward between the needles then over the top of the right needle and knit the next stitch.

If it’s before a purl stitch you bring the yarn forward between the needles as you normally would to purl then over the top of the right needle and bring it forward again between the needles and purl the stitch.

For your “Yarn forward SKP” it wants you to bring the yarn to the front and SKP.

Do you have a pattern name and link? That would help a lot. (Don’t post the pattern itself here)
