▎ 摘　　要

NOVELTY - The electronic device has a grapheme table holding unit for storing and maintaining multiple levels and a grapheme table in which multiple predetermined graphemes for each of the multiple levels are recorded. A word table holding unit for storing and maintaining a word table in which a multiple of predetermined suggested words and constituent elements constituting each of the multiples suggested words are recorded in correspondence with each other. When a first level among the multiple levels is selected by the user, a multiple of the first grapheme corresponding to the first level is extracted from the grapheme table, and then included in the multiple of the first graphene from the word table. USE - Electronic device for supporting efficient typing practice by presenting words for each level according to grapheme classification. ADVANTAGE - The electronic device correctly inputs the input word through the similarity calculation between the suggested word and the input word By confirming whether the user has done this, after receiving the input word for the suggested word from the user, it is possible to support efficient typing practice of the user. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method of operation of an electronic device that supports the practice. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic block diagram of the electronic device for supporting efficient typing practice by presenting words for each level according to grapheme classification. (Drawing includes non-English language text).
