William Shakespeare was a fan of the word. In “Much Ado About Nothing,” Leonato defends himself against Claudio and tells the soldier: “Tush, tush, man, never fleer and jest at me. I speak not like a dotard nor a fool.”
In "Taming of the Shrew," Baptista commands that Vincentio be imprisoned, saying "Away with the dotard; to jail with him."
The "Irish Monthly Magazine of Politics and Literature" from 1833 carries this sentence: "A father's stern command resigned her to the arms of a dotard. …"
The "Mirror of Literature, Amusement, and Instruction" from 1842 contains this sentence: "This old favourite, and 'father of cheap literature,' though advanced in years, is not cast off as a thing lacking in interest; a dotard in its second childhood; but, on the contrary, is now looked upon as a hoary-headed sage, abounding in humour. …"
Dotard appears to be making a comeback, thanks to Kim.
