Since Question One went so well...

First of all there is no such thing as wetness in wine. Dry means all sugar has been fermented into alcohol. Where some sugar has been left in the wine it is called residual sugar (RS). Dryness and sweetness do not determine finish. The totality of the wine determines it.

Finish is the sensations of taste, texture, and smell you continue to perceive after swallowing. The longer the better.
