MM & HP "in every other way"

Zoega: e-m vex e-t í augu, one has scruples about something.
MM & HP "let nothing deter you".
I think the metaphor is of allowing something to grow in your mind's
eye and thus to seem bigger and more daunting than it should be.

> "Svo mun vera verða,"

MM & HP "Very well". I think she's just saying that what he's told
her to do (speak more fully) is going to happen, i.e. "yes, okay, I will."

Fritzner cites this this very passage to exemplify the second of his
two definitions: Iver for, Evne til at gjøre sig behagelig for andre
"zeal/ardour for, ability/power/capacity to please one another". The
former fits with Magnús Magnússon and Hermann Pálsson's translation:
"although we both passionately desire to reach consummation." But
Cleasby and Vigfússon just has the definition "change" and the
definition which Blanc Uoden has mentioned "in modern usage chiefly
'moral conduct, acting'". But does that mean (*adopts Gandalf voice*)
"that it's chiefly in modern usage that this meaning occurs", or that
in modern usage it chiefly means "moral conduct", or that in modern
usage it means "conduct, actions", chiefly with referrence to their
morality??

Patricia, do you have different translation in your complete set of
sagas? If so, it would be interesting to know what it says here.

Strange that ardour and ability are classed together as one definition
with only one quote. Speculation: could it be that this is an unusual
or even unique use of the word in such a sense? Is "ardour" is guess
even? In which case, Alan's explanation sounds pretty convincing. Or
are there other examples with this "ardour, zeal" meaning?

most (?), rules of the Althing and common law.

MM & HP "as correctly as possible in accordance with the procedural
rules of the Althing and the common law of the land."
