Handwriting refers to a person's writing created with a writing utensil such as a pen or pencil. The term encompasses both printing and cursive styles and is separate from formal calligraphy or typeface. It is, in essence, a visible form of a person's voice, including pitch and tone.Because each person's handwriting is unique, it can be used to verify a document's writer, and the deterioration of a person's handwriting is also a symptom or result of certain diseases.
