Hebrew may be written from right to left because in ancient times when chiseling out words on a stone tablet, the engraver would hold the hammer in his dominant hand (usually the right hand) and the chisel in the left hand, making it easier to write from right to left. But as writing tools began to develop, methods like inkjet on parchment or a stylus on clay led to scribes writing from left to right so they wouldn’t smudge the letters. However, by the time this happened, Hebrew and other Semitic languages were already in “Set in stone,” so to speak, so they continued to be written from right to left.
