The search for control words returns the 10 words of the same length that are closest, under and above, to the lexical frequency of the original word. In case of more than ten words are found with the same frequency, only some of them will be displayed.

You have to select the language of the entered word that determines the corpus from which its lexical frequency will be obtained. It is possible to look for a control within the same language or to look for a matched control word in any of the other languages.
