Aha!...Aha! That is interesting. Leenwoord, erfwoord, leenheer, leenman, all familiar words from national history.
Is there a specific difference between a Lehnwort and an Erbwort?
Or does it mix and mingle a bit? To my ears the word 'fief ' is always such a funny word.
( the child with the missing front theeth trying to say 'thief ' ? )

Oh, but how about the domestication of the pronunciation of a loanword? (in general and in particular?)
(reminds me of the man who was trying to find the meaning of a Germany originated
word some time ago, but he did not remeber the pronunciation well and the word remained mystery)
looks like a little pyramid to me
