This is unrelated to the topic but TOHIGHSCHOOLGUY’s mention of the “ketuba” made me write this.
I am curious why some people pronounce all Tav’s with the hard sound “t” and never use the “s” sound. As far as I remember Tav is pronounced /t/ when there is a Dagesh Kal in it and pronounced /s/ when there is not. It’s possible that I’m wrong but I think that there is no Dagesh in the word kesuba.
Can someone explain this to me? Do you use these pronunciations in Davening as well?
