Let's analyze the two sentences:

Sentence 1: "She is proud of her face."

In this sentence, the word "face" is the object of the preposition "of". It refers to a part of the body (a thing). Therefore, "face" is used as a Noun.

Sentence 2: "Learn to face dangers manfully."

In this sentence, the word "face" comes after the infinitive "to" and has an object "dangers". It describes an action (to confront or deal with something). Therefore, "face" is used as a Verb.

Conclusion: The same word "face" is used first as a Noun and then as a Verb. This is a classic example of how many words in English can function as different parts of speech depending on their use in a sentence.

Understanding parts of speech is fundamental to grammar. A word's part of speech is defined by its function in a sentence, not the word itself. Many words, like "face", "run", or "light", can be both nouns and verbs.

• Noun: A word that names a person, place, thing, or idea.
• Verb: A word that expresses an action or a state of being.

Final Answer

The highlighted words have been used as Noun; Verb.
