Obviously, the title contains a big hint. And wosquaddle is quite understandable. But what is pho? What clue might contain -pho-?
Since this is incredibly difficult, I guess I must reveal the main idea of the puzzle.
Puzzled Pig's guess about -pho- is correct! They are indeed homophones. All of the 4 words have real meanings, however, none of them is mentioned (even implicitly) in the riddle. Instead, there is a meaning for a word (or phrase) which sounds the same as the word in the word-square.
