* Direct quotes: Biographies often include direct quotes from the subject or people who knew them. These quotes are enclosed in speech marks to indicate the exact words spoken.
* Narrative style: Biographies are primarily written in a narrative style, telling the story of a person's life. This narrative typically doesn't involve directly quoting the subject's thoughts or conversations.
* Attribution: When quoting someone, biographies will use attribution phrases like "he said" or "she remarked" to clarify who is speaking.
However, there are some exceptions:
* Direct dialogue: If a biography focuses on a particular conversation or a specific event where dialogue is essential, speech marks may be used.
* Personal letters: Biographies often use excerpts from letters written by the subject. These letters might contain direct quotes, which would be enclosed in speech marks.
Ultimately, the decision to use speech marks in a biography depends on the specific content and the author's writing style.
