Aach (toponymy)

Aach (variants Ache; Aa) is a widespread Upper German hydronym, from an Old High German aha (Proto-Germanic *ahwō) "running water" (ultimately from PIE *hakʷā- "(moving) water") The word has also been reduced to a frequent sufix -ach in Alemannic and Austro-Bavarian toponymy. The word is cognate with Old English ǣ, Old Saxon aha, Old Norse á, Gothic aƕa, all meaning "river; running water".

Related is the German Aue (variant Au) with a meaning "river island, wetland, floodplain, riparian woodland", i.e. a cultivated landscape in a riparian zone. It is derived from the same root, but with a -yo- suffix (Proto-Germanic *awjō). This word was also reduced to a suffix, as -au (as in Reichenau). It is frequent as a river name, as in Große Aue, Aue (Elbe), Aue (Weser), etc., as well as the name of a settlement, as in Aue (Saxony), Au, St. Gallen, Au, Vorarlberg, Au am Rhein, Au am Leithaberge, etc.

The river-name Aach in Upper Germany is reserved for broad, but non-navigable, running streams with noticeable gradient sufficient to power water mills; it contrasts with Fluss used for navigable rivers on one hand, and with Bach for minor brooks or rivulets. An instructive example is Salzach, now classed as a Fluss ("river") but formerly as Ache as it was only navigable by raft, not by regular riverboats.

Erik Acharius

Erik Acharius (10 October 1757, in Gävle 14 August 1819) was a Swedish botanist who pioneered the taxonomy of lichens and is known as the "father of lichenology".

Acharius was born in Gävle, matriculated at Uppsala University in 1773 and was one of the last of the students of Linnaeus. He later worked for the Royal Academy of Sciences in Stockholm and completed his medical studies at Lund University in 1782. He was appointed town medical officer in Vadstena in 1785, district medical officer in Östergötland County in 1789, director of the new Vadstena Hospital (which he had initiated) in 1795, and titular professor in 1803.

Acharius belonged to the younger generations of Swedish botanists who continued what Linnaeus had left undone. Acharius began the taxonomic classification of the Lichenes and published several work in this field: Lichenographiae Suecia prodromus (1798), Methodus lichenum (1803), Lichenographia universalis (1810), Synopsis methodica lichenum (1814) and many smaller papers in periodicals.

    Ache

    by: Jawbreaker

    I believe in desperate acts.
    The kind that make me look stupid.
    (Look like a fool)
    Just keep reinventing myself.
    It's move or die.
    (I change my form)
    These days the people I love
    are spread so far apart.
    (All out of reach)
    It's a thin sheet
    Across the face.
    (Cover me now)
    That's pretty old.
    I never felt like this before.
    I say that every hour.
    It's never going to be like it could have been.
    Now it's just this room.
    (Window looks back)
    You're a big part of it.
    But I don't care.
    (You take the lead)
    And can you really see me now
    Like I made me?
    (Made me anew)
    Just like anyone at all.
    Safer alone.
    So right, so wrong.
    Another winter's coming on.
    You win, you lose.
    It's the same old news.
    (These things go wrong so often)
    Pick up the phone
    and punch your home code.
    Somewhere, sometime let me make you mine.
    Lean your head on mine
    Like you used to.
    (Used to your lean)
    I don't mind if you're faking it.
    (Make it seem real)
    I'm not asking the questions.
    I'm not demanding the answers now.
    (Take what you give)
    Right or wrong, just take me,
    lead me on.
