suffix
Mr.; Ms.; formal addressee suffix
A polite but stiff written suffix used in official documents, business letters, certificates, and similar address lines. In modern everyday correspondence, 様 is usually safer; 殿 can sound administrative, hierarchical, or addressed from an organization to an individual or subordinate.
通知書の宛名には「山田太郎殿」と書かれていた。
The notice was addressed to “Mr. Taro Yamada.”
表
The certificate is printed with “Ms. Hanako Sato.”
A broadly polite and respectful suffix used in letters, emails, customer service, and formal address; generally safer than 殿 for addressing people today.
A common everyday honorific suffix for people; much less formal and not suited to official document address lines in the way 殿 is.
Used when addressing an organization or department rather than a named individual; 殿 is attached to an individual name, title, or sometimes a post.
The spelling uses 殿, a character associated with halls, residences, lords, and honorific address. As the suffix どの, it functions as a conventional written title; no detailed historical derivation is specified.
