I know in Norwegian at least "dedikert" means a work is *about* something, while "dedisert" means that it isn't about it, but rather credit is given to the it. A book may be "dedisert" to a person, while the Harry Potter books are "dedikert" to Harry Potter.
The piece is a triptych dedicated to the three Italian composers Luciano Berio, Bruno Maderna and Franco Donatoni.
Because the word "dedisere" is in the norwegian language, but "dedisert" is NOT in the norwegian language.
Because of this, in this sentence when something is ment to "dedisere" someone.. we have to use dedicated.
Dedisere is from german orign. dedicate is english orign. But it all goes back to the latin word dedicare...
