Etymology
The word 'chamfer' entered English in the mid-16th century from the French architectural term 'chanfrein'. This French term is a contraction of the phrase 'chant fraint', literally meaning 'broken edge' or 'song broken', where 'chant' means 'edge' or 'song' and 'fraint' is the past participle of 'fraindre' (to break). The core logic is of an edge that has been intentionally 'broken' or cut away from its original sharp, 90-degree angle. This literal sense of creating a beveled or sloping surface by removing material remains the precise technical meaning in carpentry, masonry, and engineering today.
