A great little commentary on Proverbs by Derek Kidner has some great introductory material. One of the chapters covers the subject of wisdom and I thought you'd be interested in the different words Proverbs uses for wisdom:
1. Instruction: Often used in conjunction with correction. "The two terms together can be summed up as discipline; they give the reminder that wisdom is not to be had through extra-mural study: it is for disciples only."
2. Understanding/Insight: Captures the idea of discerning between two things, usually good and evil, righteous and wicked.
3. Wise dealing: "good sense, practical wisdom, savoir-faire...Its supreme expression is in the unworldly triumph of the Servant of the Lord (Isa. 52:13)."
4. Shrewdness & Discretion: the power of forming plans. "...the godly man is in the best sense a man of affairs, who takes the trouble to know his way about, and plan his course realistically...he knows the ropes."
One of the ways I've tried to view Proverbs is as the promises God has made to Himself concerning those being conformed to the image of Jesus. This is the wisdom He has planned for me, even me! A great thought and some good, specific ways to pray for wisdom (James 1:5).
