Handheld electronic device and method for disambiguation of compound text input and employing different groupings of data sources to disambiguate different parts of input

A method of enabling input into a handheld electronic device of a type including an input apparatus, an output apparatus, and a processor apparatus, the processor apparatus comprising a processor and a memory, the memory having stored therein an alphabet and a number of objects, the number of objects comprising a number of language objects, the alphabet comprising a core alphabet portion and an extended alphabet portion, the core alphabet portion comprising a number of linguistic elements, at least some of the language objects each being comprised of a number of the linguistic elements in the core alphabet portion, the extended alphabet portion comprising at least a first linguistic element not in the core alphabet portion, at least a first language object comprising the at least first linguistic element, the input apparatus including a plurality of input members, at least some of the input members each having a number of the linguistic elements assigned thereto, at least some of the input members each having as the number of linguistic elements assigned thereto a plurality of the linguistic elements assigned thereto, the method comprising:

• detecting as an ambiguous input a number of actuations of a number of input members including an input member having the at least first linguistic element assigned thereto;
• generating a number of compound language solutions by, for each compound language solution, identifying a language object corresponding with an initial portion of the ambiguous input and having a length equal to the length of the initial portion, and identifying another language object corresponding with another portion of the ambiguous input;
• and
• outputting a representation of each of at least some of the compound language solutions, each said representation comprising a representation of the language object and a representation of at least a portion of the another language object, the representation of the at least portion of the another language object being free of the at least first linguistic element.

A handheld electronic device comprising:

• an input apparatus comprising a plurality of input members, at least some of the input members each having a number of linguistic elements assigned thereto, at least some of the input members each having as the number of linguistic elements assigned thereto a plurality of the linguistic elements assigned thereto;
• an output apparatus;
• and
• a processor apparatus comprising a processor and a memory;
• the memory having stored therein a number of objects including a number of language objects comprised of a number of the linguistic elements;
• at least some of the language objects being stored in a first data source;
• at least some of the language objects being stored in a second data source;
• responsive to detecting as an ambiguous input a number of input member actuations, the processor apparatus being structured to generate a number of compound language solutions by, for each compound language solution:
• searching both the first data source and the second data source to identify a language object corresponding with an initial portion of the ambiguous input and having a length equal to the length of the initial portion, and
• searching fewer than both of the first data source and the second data source to identify another language object corresponding with another portion of the ambiguous input;
• the processor apparatus being structured to, for each of at least some of the compound language solutions, provide to the output apparatus a signal representative of the compound language solution and comprising a representation of the language object and a representation of at least a portion of the another language object;
• and
• the output apparatus being structured to provide output responsive to said signals.
