• definitely

  The most common, neutral way to state certainty about a fact or future action; used with everyday verbs like "will" or "is", with no special emotional tone.

  表达对事实或将来行为确定性时最常见、最中性的说法；常与“will”或“is”等日常动词连用，不带特殊情绪色彩。

  I will definitely call you back after my meeting ends.

  开完会后我一定会给你回电话。

• decidedly

  Describes the noticeable degree of a quality, typically placed before an adjective or comparative (e.g. "decidedly better"), rather than expressing certainty about a fact; slightly more formal.

  描述某种性质明显的程度，通常放在形容词或比较级前（如“decidedly better”），而不是表达对事实的肯定；语气略正式。

  His mood became decidedly better after the good news arrived.

  听到好消息后，他的心情明显好转了。

• emphatically 本词

  Conveys strong feeling or forceful insistence, usually with verbs of asserting or denying (e.g. "deny", "state"), showing the speaker's emotional force rather than plain certainty.

  表示强烈的情感或坚决的态度，通常与“deny”“state”等表示断言或否认的动词连用，体现说话人的强烈情绪，而非单纯的确定性。

  She emphatically denied any involvement in the mistake.

  她坚决否认与这个错误有任何关系。

Definitely, decidedly, and emphatically all show certainty, but they differ. Definitely is the most common, neutral word for a fact or plan. Decidedly describes a noticeable degree, often before an adjective, like 'decidedly better'. Emphatically shows strong feeling, often with verbs like deny or state.

这三个词都表示某种确定或明显的态度，但语气和用法不同：definitely 最常用、最中性，用于陈述确定的事实或计划；decidedly 强调某种性质变化的明显程度，常修饰形容词或比较级；emphatically 则带有强烈情绪，常用于坚决地断言或否认某事。
