Which female character in Animal Farm has difficulty remembering commandments and suspects that they are being altered?

Clover is the female character in "Animal Farm" who faces difficulty remembering the commandments and grows suspicious that they are being altered. Throughout the novel, she represents the working class and her struggle to recall the original principles of Animalism reflects broader themes of manipulation and control within society. As she observes changes in the commandments that contradict her memories of their original intent, Clover becomes increasingly aware of the injustices being perpetrated by the pigs, especially Napoleon. This realization highlights her role as an embodiment of the disillusioned citizen who feels the weight of the corruption surrounding her.

Muriel, while she can read better than Clover and serves as a comparison, does not struggle in the same way with memories of the commandments. Bluebell and Daisy are more peripheral characters in the story, primarily functioning within the context of the dog's loyalty to Napoleon without delving into the complexities of the commandments or the broader implications of their alteration. Thus, Clover’s struggle and ultimate realization about the alterations to the commandments solidify her position as a key character representing the conflict between memory and the power of those in control.
