The present invention discloses an input-based candidate word display method and apparatus. The method comprises: adopting an input pinyin character string to search for one or more candidate words; determining whether the candidate words are allographic synonyms; if so, configuring allographic synonym prompt information for the candidate words belonging to the allographic synonyms; and displaying the one or more candidate words and the allographic synonym prompt information. In the embodiments of the present invention, a user is prompted that the candidate words are allographic synonyms, thereby reducing a probability of incorrect input and improving input efficiency.
