Which definition best describes "written instrument" in the context of forgery?

The definition of "written instrument" in the context of forgery is best described as including any document purporting to be a signature. This is because a written instrument broadly refers to any tangible representation of a person's thoughts or intentions expressed in writing, which can include signatures, contracts, checks, or any other documents that hold legal significance. Forgery laws are designed to address the act of falsifying these representations, especially those that are intended to deceive others by implying authenticity or true authorship.

In this context, the focus on documents that may appear to represent an individual's signature emphasizes the legal implications of using such documents to mislead or commit fraud. This aligns with how laws regarding forgery work, as they protect against the creation or alteration of documents that could misrepresent an individual's intent or agreement.

Therefore, the choice that accurately captures the essence of "written instrument" within the scope of forgery is one that encompasses any documents suggesting someone's signature, highlighting the broader and more inclusive definition critical for understanding forgery offenses.
