Celtic Germanic relationship

[Brian M. Scott]

>> Eg., the PrtGrmc word for "iron" is a Celtic loan, as are several
>> other terms (ruler and servant, for instance) and the form of these
>> loans indicates that they were borrowed before the first Germanic
>> sound-shift, since it underwent that change.

BJE> Do these loans provide evidence for all three consonant grades?
BJE> The only words that come to mind are *i:sarn- (iron) and *ri:k- (power),
BJE> which only provide evidence for PIE *g -> PGmc *k.

What about Goth. <andbahts>, OHG <ampahti>, ON <amba'tt> (specialized
to 'bondswoman'), etc., from Celt. <ambactus> 'Dienstmann' (here with
Latin ending)? Or OHG <Walh> from the Celtic tribal name <Volcae>?
They appear to offer evidence for PIE *k -> PGmc *h.
