dilettante: may apply to the lover of an art rather than its skilled practitioner but usually implies elegant trifling in the arts and an absence of serious commitment: a serious art teacher with no patience for ~s.  trifle泛指玩弄，如玩耍不关心轻浮


dabbler: suggests a lack of serious purpose, desultory habits of work, and lack of persistence: a ~ who never finished a single novel.    (desultory散乱无条理: 从一处跳到另一处，缺乏系统方法连贯implies a jumping or skipping from one thing to another without method or system and a consequently inconsistent performance and lack of continuity，如a desultory discussion of current events散乱地讨论当前时事)


tyro: implies inexperience and the attendant incompetence often combined with audacity resulting in crudeness or blundering: a ~ who has yet to master the basics of playwriting.  blunder通常是低级错误


amateur业余爱好者、选手: 指涉足某门艺术但未掌握必要技能的人；或参与体育比赛但不要报酬的人，dilettante也是业余爱好者: 指喜欢某门艺术但不专业不投入的人，dabbler浅尝辄止半瓶醋涉猎: 不认真不专注不坚持，tyro新手: 指缺乏经验能力欠慎重，因此做事粗糙出错
