Q.1.Two theories try to explain the origin of this extremely common usage. According to the first, it came about during the printing of the appendix of Rene Descartes' classic treatise "La Geometries". While the text was being typeset the printer ran short of certain letters in the alphabet and therefore used a single alternative for all of them. The second theory claims that its usage alludes to the Arabic root word “shei” which stands for the unknown. What usage am I talking about?
