Abstract: A linguistic phrase including a plurality of adjacently positioned characters arranged in a first sequence may be displayed. A first command may be received to obscure the linguistic phrase by separating the plurality of adjacently positioned characters into constituent characters In response to receiving the first command, the constituent characters may be displayed separate from each other to obscure the linguistic phrase. A second command may be received to combine at least two of the constituent characters to form a particular linguistic phrase including a number of adjacently positioned characters arranged in a particular sequence. Validity of the particular linguistic phrase may be evaluated. Upon determining that the particular linguistic phrase is valid, the particular linguistic phrase may be displayed including the number of adjacently positioned characters arranged in the particular sequence.
