The phrase "easy pocketbook" implies a purse or small bag that is uncomplicated to carry or use. Its antonyms, therefore, would be words like cumbersome, complex, and difficult. A cumbersome pocketbook would be one that is large, heavy, or awkward to hold, while a complex pocketbook might have multiple compartments or a puzzling closure mechanism. A difficult pocketbook would be one that is challenging to use or carry, such as one with a strap that constantly slips off one's shoulder. It is essential to choose a pocketbook that suits one's needs and lifestyle, whether it be easy, cumbersome, complex, or difficult.
