A little arch perhaps but fun all the same:

Things are a bit odd for "milk", as the verb in ancient Gk and Lat has
a "melg" / "mulg" element, clearly connected with the modern English
"milk", but the noun in Anc Gk is "galact-" (whence "galaxy") and the
Lat seems to be from the second bit of that – "lact-". Readers will, of
course, be able to check the details of this in their copies of Charles
Darling Buck’s Dictionary of Selected Synonyms in the Principal
Indo-European Languages. The info about milk is in sections 5.86-7.

Followed by:

Surely the existence of proto Indo European is almost certain. Do you
believe in Colin Renfrew’s ‘Anatolian hypothesis’ re the origin of
proto-IE, or the more standard hypotheses identifying this as one of
the steppe kurgan cultures?

What is this, the TLS now?
