A more thorough explanation:

Definition: Handwriting is a person's unique style of writing, including the size, shape, and style of letters that make their writing different from others.

Examples:

• My handwriting is very neat and small, while my friend's handwriting is big and messy.
• When I write in cursive, my handwriting looks very elegant and fancy.
• Some people have handwriting that is difficult to read, while others have handwriting that is very clear and easy to read.

These examples illustrate how handwriting is unique to each individual and can vary in size, shape, and style. Handwriting can also be influenced by factors such as education, culture, and personal preference.
