• marvelous 本词

  Slightly more formal or old-fashioned than 'wonderful'; less common in everyday American speech, often used to express admiration for something remarkable or impressive.

  比 wonderful 略显正式或有些过时；在日常美式口语中使用频率较低，常用来表达对某件了不起或令人赞叹的事情的钦佩。

  Her grandmother still calls every good meal a marvelous feast.

  她祖母至今仍把每一顿丰盛的饭菜都称作一顿极好的盛宴。

• wonderful

  The everyday, versatile choice; used constantly in casual speech for people, experiences, news, or feelings, without sounding old-fashioned.

  是日常生活中最常用、用途最广的说法；在口语中经常用来形容人、经历、消息或感受，不会显得过时。

  Thanks for the wonderful gift, you really didn't have to.

  谢谢你这份极好的礼物，你真的不用这么破费。

Both describe something extremely good. Wonderful is the everyday, all-purpose word, used constantly in casual speech for people, experiences, or feelings. Marvelous is slightly more formal or old-fashioned, less common in everyday speech, often expressing admiration for something remarkable.

这两个词都可以形容让人非常满意、超出预期的事物，但 wonderful 是日常口语中最常用的万能夸奖词，而 marvelous 语气更书面、略显老式，用得更少，常带一点惊叹的意味。两词都没有其他常用义项需要排除。
