From a halachik perspective, what are the correct ways to pronounce the ג (gimel)? Are there variant traditions? Is there an academic/linguistic opinion on how it was most likely pronounced from the time of the giving of the Torah to the writing of the Talmud? How old are the 2 variant pronunciations of the gimel (with and without a dagesh)? What are the earliest references to this distinction? Is there any halachik significance to pronouncing it one way over the other? Is it just considered a hiddur (beautification of the commandment)?
