Germanic and B-S

[Peter &/or Graham]

On this topic it is worth noting that Germanic has in part some features
which are present on one side and absent on the other:  e.g.

(a) nouns in -o- make derivatives in -a-  (B-S, not Celtic, partly in Germ)

(b) adjectives make abstract nouns in -tu:t  (Celtic, not B-S, partly in
Germ)

This supports a wave model more than a generic model.  An early separation
of Germanic (or Germ-Armenian), with later influence from both Celtic and
B-S, seems a good explanation.
