An apparatus and method for inputting characters/numerals for a communication terminal provided with a touch part is disclosed. A plurality of blocks are formed on a block main body in a touch screen keyboard of the touch part, through which designation of coordinates or selection of characters can be performed using a finger or a tool, for communications with an outside or data storage, and consonants of characters for each language are arranged on the respective blocks while vowels are arranged on a plurality of fixed blocks in at least four directions (e.g. upward, downward, left, right, and diagonal directions) in which the block main body moves. In the case of Korean (i.e. Hangeul) keyboard, Roman character keyboard, and Japanese keyboard, consonants are inputted by touching the respective blocks on the block main body, and vowels of the fixed blocks are inputted through manipulation of the block main body that moves in at least four directions.
