Hi Everyone, just joining!
I'm a self-confessed knit-geek, so forgive me for jumping right in with a semantic discussion. I can't resist!
It was a semantic question, you're asking, right aineepooh1?
Knitqueen already answered it, but I'll just further jump in by re-stating that the row is defined as working all the stitches on the needle, just one time. So if directions call for one row, you wouldn't pair it with a second row (like the purl row), to consider it complete. One row is only once across the needle. If you are working stockinette, and have just completed a purl row, and the directions say to work one more row, in that case it would be defined as knitting a row of stitches, and then doing the next thing called for in the directions.
