The word "disquietude" is rarely used in casual conversation but retains a place in more formal contexts. It conveys a deeper, often more intense, form of anxiety or disturbance than simpler synonyms like "unease" or "discomfort." Its usage typically indicates a persistent or overwhelming feeling, unlike fleeting or temporary sensations of restlessness.
In literature, the term often evokes a sense of psychological depth, where characters are embroiled in complex emotional or mental struggles. "Disquietude" is frequently used to convey the unease of individuals or communities facing uncertainty, conflict, or unrest.
