Nook (noun); Old English (Nok): a corner, a sheltered spot, a small recess.
More often than not, the wind is a nemesis on a lake if you don’t anchor up or you have not identified sheltered areas to work on, at the edges of the wind. I fish from a pontoon boat. And, if there is a downside to that vessel it is the wind as it pushes you along like a giant sail. If I don’t anchor up, in the wind, and contend with the rolling waves, dragging anchor and thwarted back casts, I look for any small ‘nook’ or length of shoreline that gives a workable area to fish.
