The embodiment of the invention provides an input method and device and a device for inputting. The method specifically comprises the steps that input strings of a user are received, wherein the inputstrings include the first input string and the second input string, the second input string is located between a starting identifier and an ending identifier, and the first input string is the inputstring free of the second input string and located beyond the starting identifier and the ending identifier; conversion processing is conducted on the first input string to obtain a first candidate item corresponding to a first language; preset processing is conducted on the second input string to obtain a corresponding processing result. By adopting the input method and device, the preset processing conducted on the second input string is achieved under the situation that the conversion processing conducted on the first input string is not affected. Especially, mixed inputting can be achievedwithout input mode switching, the input consistency in the mixed inputting process is improved, and thus the inputting efficiency is improved.
