What does rib 2 tog in knitting mean?

In knitting, "rib 2 tog" refers to a specific decrease technique used in ribbing patterns. It means to knit two stitches together in a ribbed section, typically where the ribbing alternates between knit and purl stitches. This decrease will reduce the number of stitches in that row while maintaining the ribbed texture. It is commonly used to shape garments or create a decorative element in the knit fabric.
