detecting by the processor apparatus as an ambiguous input a number of input member actuations;

generating by the processor apparatus 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 at least one of the first data source and the second data source but 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; and

outputting by the processor apparatus 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.

2. The method of claim 1 wherein at least some of the linguistic elements together form a core alphabet, the language objects stored in the first data source each consisting of a number of the linguistic elements of the core alphabet, and further comprising searching the first data source as said at least one of the first data source and the second data source.

3. The method of claim 2 wherein at least a first linguistic element not in the core alphabet is stored on the handheld electronic device, at least a first language object comprising the at least first linguistic element being stored in the second data source, and further comprising, for at least one of the compound language solutions, identifying as the language object corresponding with the initial portion the at least first language object, and outputting as the representation of the at least one of the compound language solutions a representation of the at least first language object including the at least first linguistic element and a representation of at least a portion of the another language object.

4. The method of claim 1 , further comprising searching as said at least one of the first data source and the second data source a static data source having stored therein a number of language object.

5. 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 by the processor apparatus 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 by the processor apparatus 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 by the processor apparatus 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.

6. The method of claim 5 wherein at least some of the language objects are stored in a first data source, and wherein at least some of the language objects are stored in a second data source, the language objects in the first data source each being comprised of a number of the linguistic elements in the core alphabet portion, the extended alphabet portion being comprised of linguistic elements not in the core alphabet portion, the language objects in the second data source each comprising at least a first linguistic element in the extended alphabet portion, further comprising searching both the first data source and the second data source to identify the language object corresponding with the initial portion of the ambiguous input, and further comprising searching fewer than both of the first data source and the second data source to identify the another language object.

7. 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 at least one of the first data source and the second data source but 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.

8. The handheld electronic device of claim 7 wherein at least some of the linguistic elements together form a core alphabet, the language objects stored in the first data source each consisting of a number of the linguistic elements of the core alphabet, and further comprising searching the first data source as said at least one of the first data source and the second data source.
