"More spontaneously" refers to acting or speaking in a way that is not planned or rehearsed, but rather done in the spur of the moment. Some synonyms for this phrase include "unplanned," "impromptu," "unrehearsed," "spontaneous," "off-the-cuff," "unpremeditated," and "impulsive." All of these words convey the idea of doing something without prior preparation or forethought. They are often used to describe behavior that is natural, authentic, and unscripted. When we act more spontaneously, we allow ourselves to be more present in the moment and respond to situations as they arise, rather than relying on preconceived notions or rehearsed responses.
