What is the difference between these two terms for the word «mother»?

  * おかあさん
  * ははおや

Is there a difference in politeness/register in addressing someone, our some
other form of difference between these two?

My dictionary also lists:

  * はは
  * かあさん
  * ははのみこと

as being in current usage.

Also, I cannot figure out why katakana, which is usually used for foreign
words, would also be used for two forms of mother, as listed in my dictionary,
as follows (please note, I couldn't get my input method on my Android keyboard
to input the first of these in katakana as in the dictionary, perhaps someone
can tell me how to do it).

  * おもに
  * ママン

Difference between おかあさん and ははおや
I think the relationship between お母さん and 母親 is like that of _mom_ and
_mother_ , in English.

You can translate お母さん and 母親 to _mother_ and _mom_.

* * *

I have never heard オモニ and 母の命... オモニ is Korean.  
And I hardly use ママン. It would be better if you used お母さん, 母親, or ママ.

# For example:

>   * お母さんは[既]{すで}にお[婆]{ばあ}さんになった。 - My mother has become an old lady.
>   * お母さんと[一緒]{いっしょ} - My mother and I together.
>     * There is a TV program called
> [おかあさんといっしょ](http://www.nhk.or.jp/kids/program/okaasan.html) in Japan.

お母さん (okaasan) is the polite form of "mother". You use it to address your own
mother or when talking about the mothers of other people.

母親 or just 母 (haha) is the plain form of "mother". You use it to be humble
when talking about your own mother to other people, or when politeness is not
necessary.

The main difference is that you can't use はは to talk about someone else's
mother. I think you must use お母さん in that case. Usually Japanese people call
their mothers おかあさん when they talk to them directly. はは is used to talk about
your mother to other people.
