I've been looking at sock and Entrelac patterns, and they all say to "turn" after knitting a few stitches of the row. For example, here is the Base Triangles section of an Entrelac pattern I'm looking at:
CO 24 sts.
*Row 1: (RS) k1, turn
Row 2: and all WS rows: purl all sts in that section
Row 3: sl 1, k1, turn
Row 5: sl 1, k2, turn
Row 7: sl 1, k3, turn
Row 9: sl 1, k4, turn
Row 11: sl 1, k5, turn
Row 13: sl 1, k6, turn
Row 15: sl 1, k7. Do not turn.*
Repeat from * to * to end of row, turn.
Can some helpful person please explain what turning is?
