sinne und » sinn und, sonne und
yan guan » gan guan, yan yuan, yang guang
vu sinne » im sinne
und john » und johann
wong sau » wong sam, wong siu, wong shiu

• Adding a wildcard symbol may retrieve word variants: (wang or wan) ((yan guan) or (yang yang)) vu sinne und john ((wong sau) or (kong sar)) ;*.
