Origin of あしからず


Could somebody explain the origin of あしからず , as found in the following
expressions?

> 今回はお断りしますが，どうぞあしからず| This time I have to say no, I hope you don't mind.
>
> ・・ですが、 悪しからず。| I'm sorry but.....
>
> パーティーに伺えませんがあしからず| I'm sorry, but I can't come to the party.

The kanji is 悪しからず so it is something similar to 悪いけど／すみませんが/This is not very
good but.... But, what is the verb and where does it really come from?

asikarazu is the negative form of the adjective
[asii](http://dic.yahoo.co.jp/dsearch?p=%E3%81%82%E3%81%97%E3%81%84&stype=0&dtype=0&dname=0ss),
not a verb. That being the case, adjectives acquire much of their conjugation
via suffixation of the verb ar-. This is asiku + arazu, and the u drops. arazu
is the verb ar- in irrealis + negative -zu.

Another example of this construction would be 必ず ie 仮 + ならず which also fits
this 形容動詞 + ならず pattern

(Note: When used to apologize, sum-i-mas-e-n means "(I have done something
rude to you, and my feelings) are not at rest". When used to be thankful, the
sense is "(I am unable to return the favor, and my feelings) are not at rest".
It was not my intention to say that all sumimasen is a contraction for ki ga
sumanai / sumimasen. Phonologically that is not very likely. Rather,
grammatically, a single adjective or verb can be a complete sentence. Many
things are not said when unneeded. As such, I was filling in the missing
blanks to assist with compression. If it helps to interpret asikarazu, think
of it as 気を悪くしないで or 悪く思わないで. )
