diem romani » dem roman, die romane, die romantik
transport a » transport _, transport data
de roman » der roman, dem roman, du roman
luis a » luis f, luis c
a cash » a case
a asa » _ asa, δ asa
sur a » sur la, sgr a, sul a

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( luis ((de roman) OR (diem romani)) transport a asa ) OR ( luis a cash transfers sur a ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis ((de roman) or (diem romani)) transport a asa ) or ( luis a cash transfers sur a ))*.
