Purl through front loop is not a term you will encounter often since purling through the front loop is the basic purl stitch.

To make this stitch insert the right hand needle into the working stitch from right to left, the tip of the right hand needle will point left and towards you, wrap the yarn around the right hand needle and pull through the stitch sliding the worked stitch off the left hand needle and leaving the new stitch on the right hand needle.
