A splashback is the piece of wall behind a kitchen sink, a cooker, or a bathroom basin that is covered with tiles, glass, or steel so that water and cooking oil hit it instead of the bare wall — and so you can wipe it clean. It is a building and kitchen-design word: you meet it in shops, in home-improvement programmes, and when someone is fitting a new kitchen. The word is British, Australian, and New Zealand English; in American English people say 'backsplash' for the same thing, so if you read an American website you will see the two halves the other way round. It is countable (a splashback, two splashbacks). You will also see it used for the material itself, not just the area — 'a glass splashback', 'we chose a marble splashback'. There is a second, quite different use in medicine and safety talk, where splashback means liquid bouncing back at you when it hits a surface, but the wall meaning is the common one.
