Etymology
The word 'sandblast' is a transparent 19th-century English compound, formed by directly combining two native Old English elements. 'Sand' has ancient Proto-Indo-European roots, related to the concept of grinding or crushing, which perfectly describes its abrasive function. 'Blast' originates from a Germanic base meaning to blow, evolving to signify any powerful, directed stream. The compound's logic is entirely literal: it names a process where sand is propelled in a blast. This straightforward mechanical description reflects the industrial era's innovation in surface treatment, where the ancient materials of sand and air were harnessed with modern force.
Analysis

- sand: (Old English) From Proto-Germanic sandam, referring to the granular material. In this compound, it denotes the abrasive medium used.
- blast: (Old English) From Proto-Germanic blēstaz, meaning a blowing, gust, or strong current of air. In this compound, it denotes the forceful projection of the medium.
