もう for "already" and もう for "another"


After studying the difference between もう and まだ (which seems clear to me now),
I realize that there seems to be two different words spelled もう, which
apparently have different pitch accents; high to low for the もう meaning
"already", low to high for the (additive?) もう meaning "another".

Are they actually different words and are those definitions correct? I don't
seem to find much information concerning the pitch accents as well as the
proper definitions in Japanese dictionaries (because my level is too low and
Google Translate isn't accurate).




もう meaning "another" does have a low-high pitch accent and is used like this:

  * もう【LH】3分  
another three minutes

  * もう【LH】1回  
once more

  * もう【LH】少し  
a little more

  * もう【LH】片方  
the other one (of a pair)

もう meaning "another" is always followed by another word, and is pronounced
like one compound (see [this
discussion](https://japanese.stackexchange.com/a/56964/5010)).

Still, two monolingual dictionaries I checked explain those two types of もう
under the same entry, so they're two different usages of the same word.
