The ancient word ‘Lad’ is a solution to this problem.
It finishes the first word (it turns out ‘Office’) and begins the second (it turns out ‘Rook’).
The feeling does not leave that there is some other option, but it cannot be invented.
Here we are presented with a fairly famous task from numerous tests to IQ level. Guessing the right answer will not be difficult. The word fret is perfect for us here. The butt forms with the beginning, and with the end of the rook.
Well, something like this: the butt and boat. This is the word. I got it like that. I really did not understand: whether after the insertion of the desired word the original word should be used?
