Don't know where else to ask this.....But, in Hebrew, what's the purpose of that infuriating and (as far as I can tell) grammatically pointless two-dot shewa looking thing in the sofit form of the letter kaf? Anyone can help me with it? If it's trying to harden the sound a simple daghesh is all you need. I want to rip those Kaf's from the page and beat them up. What am I missing?
