The antonyms for "come to order" are "chaos," "disorder," and "disarray." When a meeting or gathering is described as having come to order, it implies that things were previously unsettled or unorganized, and have now been brought under control. The opposite of this would be a situation where everything is chaotic, unruly, and lacks structure or discipline. This could happen due to a lack of effective leadership, unclear guidelines, or general confusion. It is important to establish some order to avoid confusion, ensure productivity, and achieve successful outcomes. Therefore, it is vital to ensure that any meeting or gathering is well-organized, with clear agendas and established procedures, to prevent confusion and chaos.
