Some examples are further directed to detecting, in response to evaluation of the second portion of the word against the plurality of words, that the second portion of the word is one of the plurality of words. Some examples are further directed to modifying presentation of the word in response to detection that the second portion of the word is one of the plurality of words prohibited for presentation via the GUI.
