pessoptimist
A person who possesses elements of both pessimism and optimism.
The paradoxical view of the dynamics of the situation explains the meaning of the word “pessoptimist,” coined from the partial merger of “optimist” and “pessimist.”
Where it comes from
Blend of pessimist + optimist, coined by British translator Trevor LeGassick in his 1985 translation of Emile Habibi's 1974 Arabic-language novel The Secret Life of Saeed: The Pessoptimist.
