Here are glossaries from four early knitting-book writers, three of them English and the other American.
Note that Mrs. Copley is the only one to not use or even mention the word "seam" for the purl stitch!
From My Knitting Book by Frances Lambert (1843), using English terms --
Explanation of Terms used in Knitting.
To cast on.—The first interlacement of the cotton on the needle.
To cast off.—To knit two stitches, and to pass the first over the second, and so on to the last stitch, which is to be secured by drawing the thread through.
To cast over.—To bring the cotton forward round the needle.
To narrow.—To lessen, by knitting two stitches together.
To seam.—To knit a stitch with the cotton before the needle.
To widen.—To increase by making a stitch, bringing the cotton round the needle, and knitting the same when it occurs.
A turn.—Two rows in the same stitch, backwards and forwards.
To turn.—To change the stitch.
To turn over.—To bring the wool forward over the needle.
A row.—The stitches from one end of the needle to the other.
A round.—A row, when the stitches are on two, three, or more needles.
A plain row.—That composed of simple knitting.
To pearl a row.—To knit with the cotton before the needle.
To rib.—To work alternate rows of plain and pearl knitting.
To bring the thread forward.—To bring the cotton forward so as to make an open stitch.
A loop stitch.—Made by bringing the cotton before the needle, which, in knitting the succeeding stitch, will again take its own place.
To slip or pass a stitch.—To change it from one needle to the other without knitting it.
To fasten on.—The best way to fasten on is to place the two ends contrariwise, and knit a few stitches with both together. For knitting, with silk, or fine cotton, a weaver's knot will be found the best.
To take under.—To pass the cotton from one needle to the other, without changing its position.
Pearl, seam, and rib-stitch—All signify the same.
