2. Formality: The degree of formality used in business correspondence can depend on the relationship between the parties and the culture of the organization. In general, it is better to err on the side of being too formal rather than too informal.

3. Deference: This refers to showing respect for someone because of their position or authority. In business correspondence, it is important to show deference to superiors and clients. However, this should not be overdone as it can come across as insincere or obsequious.

4. Etiquette: This refers to the customary code of polite behavior in society or among members of a particular profession or group. In business correspondence, it is important to follow the accepted norms and rules of etiquette. This can include everything from the format of the letter or email, to the way you address the recipient, to the tone of your language.

5. Seriousness: Business correspondence is not the place for jokes or casual language. It is important to maintain a certain degree of seriousness to show that you take the matter at hand seriously. However, this does not mean that the correspondence should be devoid of warmth or personality.

In conclusion, the right degree of respect, formality, deference, etiquette, and seriousness should be used in business correspondence. The exact degree will depend on the context and the relationship between the parties.
