不足英文怎么说

缺点 [词典] shortcoming; defect; weakness; weak point; blemish; [例句]事事不免有缺点。Everything has its drawback.不足 [词典] insufficient; deficiency; not enough; less than; fall short of; [例句]我受到了信息不足的牵累。I was hampered by a lack of information.

imperfect,sth to be perfected/improved,多了，还是要看具体的话

应该再提供详细一点的语境常用的有这么几个deficiency缺乏不足shortcoming缺点disadvantage不利之处mistake错误fault过错这些是名词其余的都是形容词了我觉得你要的应该是名词吧
