Long ago there was an invitation on Cybalist to discuss the phonation
differences between PIE roots of very similar meaning. Did it ever happen?
On the same topic, I also recall reading an unconvincing article by Swadesh
(in the journal 'Word'?) discussing the l~n~r alternations at the start of
IE words. I recall that he used dictionaries of modern languages to make
his comparisons. He suggested that contrasts between 3 varieties of [l], 3
of [r] and 3 of [n] had collapsed to a single 3-way contrast.
