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.
rib Yeah this is a ribbing stitch. After you knit a few rows it should be a very clean and neat looking pattern of purls and knits.
In knitting, k2tog is an abbreviation for "Knit Two Stitches Together," or simply "Knit Two Together."
knit 19 stitches or rows (depending on the context)
P2 means purl two stitches as K2 means knit two stitches.
K2 is simply knitting for two separate stitches. this is different from K2tog which means knit two together, where you treat the next two stitches as though they are one.
In knitting, a rib is a type of stitch pattern created by alternating knit and purl stitches (For instance, Knit 1, purl 1 or knit 2, purl 2). This technique creates vertical, textural stripes called ribs. There are many variations on rib stitches.

It just means to knit (the knit stitch) for 3 rows. No increases, no decreases, no pattern stitches.
2x2 rib refers to K2P2 ribbing. K2P2 ribbing means that you alternate two knit stitches with two purl stitches across the width of the work. Similarly, 1x1 ribbing is sometimes called K1P1 ribbing, and you'd alternate knits and purls across the work. Other sorts of ribbing my be notated as 3x1 (K3P1) or 3x2 (K3P2). The total length and width of the pattern (of whatever ribbing you are knitting) will be specified by the particular pattern that you are knitting. The number (1,2,3...) with the ribbing only specifies how wide the ribs will be.
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.
Knitting slippers is simple. Cast on 29 stitches. Knit as many rows as you need to fit your foot. Then start knit knit purl purl for as many rows as you need. Cut a tail and pull a plastic needle through the stitches. Take it off the needle along with the stitches and pull tight. Then sew in and out of the slipper. do the same thing with the tail at the end of the slipper.
When you reach the slip knot, knit it just like all of the other stitches, throwing it off at the end just like the other stitches. When you have knit the slip knot, all of the stitches should be on the right needle, and the left needle should be completely free*.*There may be some exceptions to this rule, as in circular knitting, but this will not be addressed until you are an advanced knitter, and you don't have to worry about that right now.
It means one of two things, depending on how the pattern is written. 1. Perform knit stitches to the end of the row. or 2. Continue in pattern to the end of the row. If the pattern instructions include parenthesis or asterisks just prior to the instruction to knit across, then option 2 is intended. Otherwise it is option 1.
