RONDDÉL - round yard, round-part, rampart

Artists impression of circular rampart
of Burg near Celle, Germany

A little one, just for the record:

ROND
round - English
rond - Dutch
rund - German, Danish, Swedish, Norse
rûn - Frisian

DÉL
deal, part - English
deel - Dutch
Teil - German
del - Danish, Swedish, Norse
diel - Frisian

Aggersborg Denmark

Trying to find a good translation for ROND.DÉL (see six fragments below), I stumbled upon "rampart", which seemed to fit pretty well and made me wonder if the words might be related, since DÉL means "part" and ROND- could have changed into "ram-).

The fact that ring-forts and circular ramparts were a common phenomenon in ancient Northern Europe, makes me wonder why the English language would have had to borrow from French: re-emparer (as is the official etymology). This is not impossible, but it does not make much sense to me. (Note the other word ráth for ring-fort may be related to German Rad - wheel)

Round-deal => round-part => rampart could be an alternative etymology.

Those who had gained a front yard to their house for good deeds,
were promised a back yard on behalf of the Magus.
Who had gained a front- and back yard already, was promised a round yard
and who had a round yard, a whole state.

Everyone must be given an arable back yard behind his house,
but no one may have a front yard at his house let alone a round yard.
Only if one has done a deed serving the common good
that may be given him
and his youngest son may inherit it,
but after that the village must take it back.

If the king wants, he may choose a place on an uncultivated site for his house and domain.
That domain may be a round yard so large
that he can walk seven hundred steps from all sides out of his house
before he reaches his boundaries.

As dad has mentioned, the haveless people went
and built small houses within the ring-dike of the burg.
Therefore that rampart is now called Ljudwérd*.
