Portuguese Formal salutations The standard formal Portuguese salutation uses an addressing expression such as Caro (Dear) or Excelentíssimo Senhor (Most Excellent Sir), followed by the addressee titles (e.g. Eng.) and addressee name. Most expressions must be modified to account for addressee gender and number. Caro, for example, becomes: Caro for a man; Caros for a group of men or a mixed group of men and women; Cara for a woman; Caras for a group of women. The formal expression Excelentíssimo Senhor is often abbreviated as: Exmo. Sr. for a man; Exma. Sra. for a woman; Addressee titles can be professional and are often preceded by Sr. (Mr.) and almost always abbreviated (e.g. Arquitecto – Arq. (Architect), Engenheiro – Eng. (Engineer), Padre – Pe. (Priest)). An exception to this rule is the Medical Doctor (Médico Doutor), often addressed as Doutor, being the abbreviation Dr. instead used to address anyone holding a baccalaureate degree. Each military or ecclesiastic rank has one abbreviation, and, historically, nobility ranks also had one—for example, one of the ways of addressing the Portuguese Monarch would be Sua Majestade (Your Majesty) abbreviated as S.M. . The title Sr. (Mr.) can also be used on its own, when appropriate. Informal salutations Informal salutations may or may not be followed by the name of the addressee, and almost never contain any titles. Olá (hello) Oi (hi) Querido / Querida (informally, Dear) Romanian Formal salutations When addressing a formal letter whose recipient is not known by name, the salutation of preference is Stimate Domn, Stimată Doamnă (equivalent to Dear Sir or Madam in English).
