The key difference between formal and friendly letters lies in their salutation punctuation. Formal letters to teachers, principals, business owners, or government officials require colons after the greeting. Examples include "Dear Mayor Johnson:" or "Dear Dr. Smith:"
Friendly letters to family members, friends, or classmates typically use commas instead of colons. Writing "Dear Grandma," or "Dear Alex," creates a warm, personal tone. Understanding this distinction helps writers choose appropriate punctuation for their audience, similar to mastering formal vs informal language.
Common Salutation Punctuation Examples
Business letter salutations always use colons: "Dear Hiring Manager:" "To Whom It May Concern:" "Dear Customer Service:" These formal greetings establish professional communication standards.
Personal letter salutations use commas: "Dear Mom," "Dear Best Friend," "Dear Cousin Sarah," These friendly greetings create intimate, casual communication. Mastering both styles prepares students for various writing situations, building on skills like quotation marks for direct quotations.
