The term "more longcontinued" implies something that persists for an extended period. However, if you want to express the opposite meaning, you can use antonyms like "brief," "short," "intermittent," "sporadic," "fleeting," or "transient." "Brief" denotes something that lasts for a short period; "short" refers to the duration of an event or action. "Intermittent" suggests something that occurs at irregular intervals, while "sporadic" refers to something that happens occasionally. "Fleeting" denotes something that lasts only for a moment, and "transient" describes something that is temporary or short-lived. So, if you want to convey the opposite sense of "more longcontinued," you can use these antonyms appropriately.
