pan-

From Meillet's Latin Etymological Dictionary

'panna' "pan" is not from 'patina'

loaned into
OHG pfanna
Western French 'pan', 'pon' "vessel, container"
Portuguese 'panela'
Britannic 'pann' "bowl, cup"

from my failing memory:
Britanic place names 'pen-' "head" ?

That this 'vocalisme a, mot populaire' (ie. loanword) word should be
loaned into Germanic, Celtic and Romance from Latin is not the only
viable possibility (ie. Nordwestblock).
