An electronic device is provided. The electronic device includes a display and at least one processor, wherein the at least one processor can be configured to identify a first tilt between a first handwriting input displayed on the display and a first preceding handwriting input that precedes the first handwriting input, the first handwriting input corresponding to a first block, identify a second tilt between a second handwriting input displayed on the display and a second preceding handwriting input that precedes the second handwriting input, the second handwriting input being continuous to the first handwriting input, use the first tilt and the second tilt to determine whether the second handwriting input corresponds to the first block or corresponds to a second block differing from the first block, and perform, based on the second handwriting input corresponding to the second block, at least one operation for processing a plurality of handwriting inputs indicating the second block.
