False

The underlined article in the sentence "He is an honest man" is not a definite article, but an indefinite article. Definite articles are used to refer to a specific noun, while indefinite articles are used to refer to a non-specific noun. In this sentence, "an" is used to introduce the noun "honest man," which does not refer to a specific individual but rather any honest man in general.

Explanation:

Let's break down the sentence to understand it better:

- Subject: He
- Verb: is
- Noun phrase: an honest man

In this sentence, the indefinite article "an" is used before the noun phrase "honest man" to indicate that we are referring to any honest man, not a particular or specific one.

Definite Article:
Definite articles are used when we are referring to a specific noun that both the speaker and the listener are aware of. In English, the definite article is "the." For example:

- "The book on the table is mine." Here, "the" is used to refer to a specific book that is on a particular table.

Indefinite Article:
Indefinite articles are used when we are referring to a non-specific noun. In English, the indefinite articles are "a" and "an." We use "a" before words that begin with a consonant sound, and "an" before words that begin with a vowel sound. For example:

- "I saw a cat in the garden." Here, "a" is used because "cat" is a non-specific noun, and it does not refer to a particular cat.

In our given sentence, "He is an honest man," the indefinite article "an" is used before the noun phrase "honest man" to indicate that we are referring to any honest man in general, not a specific one.

Therefore, the correct answer is False, as the underlined article is an indefinite article, not a definite article.

False because" an" is an indefinite artice.
