I dont have the time to write the function for you, but it would go something like this:

words = text.split()
i = 0
while i < len(words) - 1:
      w1, w2 = words[i:i+2]
      if not dictionaries.recognized(w1) and not dictionaries.recognized(w2) and dictionaries.recognized(w1 + w2):
         words[i] = w1 + w2
         words[i+1] = ''
         i += 1
      i += 1
return ' '.join(words)
