Schoon water.

The Dutch phrase 'Schoon water' directly translates to 'clean water' in English. The word 'schoon' has its roots in Old Dutch 'scōni' and Old High German 'scōni', meaning beautiful, bright, or clean. It is related to the English word 'sheen'. Over time, the meaning evolved to primarily denote cleanliness. The word 'water' comes from Proto-Germanic 'watōr' and Proto-Indo-European 'wodōr' or 'udōr', which are common ancestors for many words for water across Indo-European languages, including English 'water' and German 'Wasser'. The combination 'schoon water' emphasizes the purity and drinkability of the water, distinguishing it from water that might be merely 'clean' in appearance but not safe for consumption. Historically, access to clean, potable water has been a significant concern, and this phrase would have been vital in indicating a reliable source. The concept of 'pure drinking water' further refines this, highlighting its suitability for human consumption without needing further treatment.
