mo:chten vs mo:gen?
I am told these both mean 'want' but why use one or the other?
"Möchten" is the politer form. Never say in a restaurant "Ich mag Kartoffeln", one says "Ich möchte Kartoffeln".
I am not 100% sure but it seems to me that "möchten" is the Konjunktiv II of "mögen" but it is usually studied as another completely different verb on its own because it is more used than the Präsens form. If someone can confirm or deny this, please...
@IdontKnow, it looks like you are right. The Pons language portal has möchten as the conjunctive of mögen (http://en.pons.eu/dict/search/results/?q=m%C3%B6gen=deen=ac_undefined=de). Grimm Grammar lists it among the modal verbs, and has möchten as a softer form of mögen (http://coerll.utexas.edu/gg/page.php?p=vm_01). Grimm Grammar also implies that although möchten is a form of mögen, it has a life of its own.
