Etymology
The word 'sandblasting' is a modern compound formed from two Old English roots. 'Sand' has a straightforward history, referring to the granular abrasive material used in the process. 'Blast' evolved from the Old English concept of a forceful gust of wind to denote any powerful stream of air or particles. The combination, with the gerund suffix '-ing', logically names the industrial technique where a high-velocity stream of sand is directed at a surface to abrade it. This term exemplifies how ancient, concrete Germanic roots can be recombined to describe precise technological processes.
