The opening two words of Kaddish begin with the words:
יִתְגַּדַּל וְיִתְקַדַּשׁ
Both the gimmel and the dalet of 'Yisgadal' carry a dagesh as does the dalet in 'veyiskadash' - normally a function of the dagesh is to tell us where to stress the emphasis of the word but in the these two words which syllable/letter do we make the stress on?
I always learnt to say it on the end of each word - namely yisgadal veyiskadash however I have heard some people say it with the stress on the first letters i.e. yisgadal veyiskadash.
What is the more grammatically correct pronunciation and what reason do those who do differently employ?
