* Adroit means skillful, clever, or adept at something. It implies a practical and efficient ability.
* Pollyannish describes someone who is excessively optimistic and cheerful, often to the point of being unrealistic or naive. It implies a particular attitude or mindset.
Here's an example to illustrate the difference:
* Adroit: "The magician was adroit at sleight of hand, making the rabbit disappear with a flick of his wrist."
* Pollyannish: "Despite facing difficult circumstances, she remained pollyannish, believing everything would work out for the best."
While both words can describe positive qualities, adroit focuses on skill and ability, while pollyannish focuses on a specific optimistic outlook.
