bole
UK[bəʊl]US[boʊl]
n
The trunk of a tree.
Etymology
The word 'bole' has a direct and ancient lineage, tracing back to the Proto-Germanic root bul-, which conveyed the sense of something round or swollen. This root gave rise to words for both rounded containers (like 'bowl') and the rounded, main stem of a tree. The specific form 'bole' entered Middle English from Old Norse, a language rich in terms for natural features. Over time, its meaning narrowed and stabilized in English to refer specifically to the trunk of a tree, preserving the core idea of a substantial, rounded cylindrical form found in nature.
Analysis
This word is a simplex form. It is derived from Old Norse bolr, meaning "tree trunk" or "rounded object," which is of Germanic origin and related to Old English bolla (bowl, rounded vessel).
Examples
The ancient oak had a bole so wide that three people could not encircle it with their arms.
Moss and ivy clung to the rough bole of the pine tree.
Foresters measured the diameter of the bole to estimate the tree's age and volume.
