This does not make them loan words! Any more than French chanter is a loan
from Italian cantare. They are inherited in both PIE and Semitic (or
whatever). Bomhard is setting out to show how PIE and certain other
language groups share a common origin. If he is right in connecting these
words, then they are inherited words within PIE, and also in whatever other
language group they are found in. Bomhard's whole thesis collapses if all
these words are loans, and he tries deliberately to exclude loans so as not
to skew the evidence.
