Does anybody know of decent theoretical study on shva merahephet, whether a
book, Internet publication, or perhaps a synopsis?
I mean, lexicological explanation beyond the mere fact that the concept of
shva merahephet explains known anomaly?
Perhaps you would also know when the use of dagesh in segollate (is this the
correct word in English?) was first documented? That is, do we have
extra-Masoretic spelling with dagesh in lamed?
By the way, speaking on the earliest documented usage, do you happen to know
when suffix hem (haf-mem) first became stressed?
