Should countersign be hyphenated

Answer 1

The term "countersign" is typically not hyphenated. It is commonly used as a single word in both legal and general contexts to refer to the act of signing a document for verification. However, if it’s used in a way that emphasizes its components (like "counter-sign" in a specific context), hyphenation might be acceptable, but it's less common. Generally, it's best to use "countersign" as one word.
