There are several sites that offer tutorials on how to get started at a purl stitch including Knitting Help and Knitting Daily. One can also go to a book store such as Barnes & Noble and read a knitting for beginners book.
The verb is "purl". Thus, to invert a stitch is to purl.
You Purl one stitch, then repeat it.
Purling is knitting the purl stitch.
If you are alternating each stitch (knit, purl, knit, purl) the pattern is called ribbing. If you alternate each row (row 1 knit, row 2 purl) it is called stockinette stitch.
Stocking Stitch (knit a row, purl a row, repeat)
if you are doing stocking stitch you can just reverse it to make a textured pattern so on knit side you would purl the stitch and on purl side you would knit it.
Usually it means to knit every stitch in a row, or if on the purl side to purl every stitch. Consider it synonymous with stockinette stitch.
Seed stitch is also known as moss stitch. It is when you knit one purl one throughout but in the next row the purl stitches are above the knit stitches in the previous one (like a chequerboard) unlike ribbing where the knit and purl stitches stay in the same column.
it is an abbreviation for Stockinette Stitch also known as Stocking stitch . It is basic stitch where you knit one row and purl one back and repeat just these two rows written as Knit 1 row Purl 1 row Knit 1 row Purl 1 row
stockinette or stocking stitch means knit one row, purl one row. So four rows are knit one row, purl one row, knit one row, purl one row.
If it's purl, it's not knit. If you do all purl stitches you get exactly the same fabric as all knit stitches, i.e. garter stitch. This is a rougher looking finish than stocking stitch, but has the advantage of lying flat.
garter stitch is when the rows alternate knit, purl, knit, purl. Since purl is the reverse of knit, for a scarf you just have to set aside a few stitches for your border on either side and knit all of them every row.
