Helge Fauskanger coined this neologism as aupsar- “wipe away” for his Neo-Quenya New Testament (NQNT), a combination of au- “away” and psar- “rub”. This neologism is rather dubious because normally a diphthong like au cannot occur before a consonant cluster like ps. I think it would be better to use öapsar- where the initial element is öa “away”.
