Origin and history of wegotism

1714, "too frequent use of 'I'," from ego + -ism. First used by Joseph Addison, who credits the term to "Port-Royalists" who used it in reference to obtrusive use of first person singular pronoun in writing, hence "talking too much about oneself." Meaning "self-conceit, selfishness" is from 1800. The -t- is abnormal, perhaps by influence of dogmatism.

plural of I, Old English we, first person plural pronoun, "I and another or others," from Proto-Germanic *wejes (source also of Old Saxon wi, Old Norse ver, Danish vi, Old Frisian wi, Dutch wij, Old High German and German wir, Gothic weis "we"), from PIE *we- (source also of Sanskrit vayam, Old Persian vayam, Hittite wesh "we," Old Church Slavonic ve "we two," Lithuanian vedu "we two").

The "royal we" (use of plural pronoun to denote oneself) is at least as old as "Beowulf" (c.725); use by writers to establish an impersonal style is also from Old English; it was especially common 19c. in unsigned editorials, to suggest staff consensus, and was lampooned as such by 1833 (compare weism, wegotism).

We is sometimes, like they, vaguely used for society, people in general, the world, etc.; but when the speaker or writer uses we he identifies himself more or less directly with the statement ; when he uses they he implies no such identification. Both pronouns thus used may be translated by the French on and the German man : as we (or they) say, French on dit, German man sagt. [Century Dictionary]

Paired with they by 1926 to indicate mutual exclusion and conflict.

"(too) frequent use of the pronoun 'we,' " 1800, from we + -ism. Compare wegotism.
