Nosism


Nosism, from Latin nos 'we', is the practice of using the pronoun we to refer to oneself when expressing a personal opinion.
Depending on the person using the nosism, different uses can be distinguished:

Royal ''we''

The royal we, or majestic plural, is employed by a person of high office, such as a monarch, bishop, or pope.

Editorial ''we''

The editorial we is a similar phenomenon, in which individual editorial columnists in newspaper or a similar commentators in other media refers to themselves as we when giving their opinion. Here, the writers cast themselves in the role of spokespersons: either for the media institution that employs them, or on behalf of the party or body of citizens who agree with the commentary.

Author's ''we''

The author's we, or pluralis modestiae, is a practice referring to a generic third person as we :
We in this sense often refers to "the reader and the author" because the author often assumes that the reader knows and agrees with certain principles or previous theorems for the sake of brevity.
This practice is discouraged in the hard sciences, social sciences, humanities, and technical writing because it fails to distinguish between sole authorship and co-authorship.
