distrust
This term conveys a proactive state of suspicion or a lack of confidence in the integrity of another. It often implies a reasoned or evidence-based skepticism, whereas mistrust can sometimes feel more instinctive or emotional. In professional or political contexts, it describes a systemic failure of confidence between two parties. As a noun, the word is typically used as an uncountable mass noun when referring to the general feeling of suspicion. While it can occasionally be used in a countable sense to describe specific instances of doubt, it most frequently functions as an abstract quality that cannot be pluralized.
Meanings
