"… before vowels, di-, word-forming element meaning
'through, in different directions, between,' also often
merely intensive, 'thoroughly, entirely,' from Greek
dia 'through; throughout,' probably cognate with bi-
and related to duo 'two' (from PIE root *dwo- 'two')
with a base sense of 'twice.' "
A midrash for Heidegger —
Here "PIE" does not refer to food. It is an acronym
for "Proto-Indo-European."
See as well "Language Animal" in this journal.
