Ambivalence
Etymology
Coined around 1910 by the Swiss psychiatrist Eugen Bleuler as German “Ambivalenz,” from Latin “ambi-” (both) and “valentia,” strength, from “valere,” to be strong. Bleuler introduced it to describe the coexisting opposite feelings he observed in his patients, and the term passed from clinical psychiatry into general use.
noun · /am-BIV-uh-luhns/
The simultaneous holding of contradictory feelings toward the same person or thing.
What it names
The genuine pull in two directions at once — loving and resenting, wanting and dreading — without either side winning.
Example
She felt deep ambivalence about the promotion, proud of the recognition yet dreading the hours it would swallow.
