same in English
Not sure if you understand the name of the thread... originally about translating Polish sayings/idioms directly into English and seeing if people could identify them like to look for wind in a field and say what they meant...
A reverse riddle is to do the same in reverse... translate an English expression into Polish. Muszę rozmawiać z kimś o koniu is that. Interestingly, while doing research before posting... the expression has a different... range(?) of meanings in the US and UK....
