@ funf - That's because you are not immersed into German language and culture. Schicksal is a wonderful old word, combining "schicken" = to send and "sal", a
Germanic suffix describing an abstract matter. When Germans can use an original German word for something they generally do, hence the prevalance of Lungenentzündung over Pneumonie. A synonym for Schicksal is Geschick, something that is sent to you. Not much difference to destiny, something that is decided for you; both are based on the philosophy of a higher being determining our fate.
See also Scheusal, Mühsal, Labsal. Mmmmmm, Labsal --- I can just feel the salutary shock of a chilled fermented mixture of starch, H2O and cereal hitting my epiglottis after gently stroking my fungiform papillae with the ennervating bitterness of hops, the sweetness of starch and the refeshing sparkle of darred barley. Damn, no beer in the house.
Ungemach doesn't work for me. Gemach is a room, Un is huge (s.a. Unwetter, Ungeheuer), so Ungemach should be a large room. Instead, it's bad luck.
