A long stick with a pointed end, used by climbers to help them walk on mountains and keep their balance.
The climber used an alpenstock to help navigate the steep terrain.
Alpenstock → The word is formed from 'Alpen' (from German 'Alpen', meaning the Alps) and 'stock' (from Old English 'stocc', meaning a stick or post). An alpenstock is a stick used for support while walking in the Alps.
Think of the 'Alps' where this stick is commonly used, and 'stock' meaning a stick — an alpenstock is a stick for walking in the Alps.
