'rudeigin' doens't seem to follow the flanking rule.
is this because -eigin is basically a suffix?
The few words that don't follow the rule are usually words that used to be hyphenated. So rudeigin used to be spelled rud-eigin :)
cool. so does the -eigin suffix mean basically 'any', the same way any is a prefix in english?
can it be appended to other words as needed, or is it only used for specific words (rudeigin, cuideigin, etc)
