Explanation:

As we know, an adjective is a word that modifies a noun or a pronoun by attributing a quality to it. A compound adjective and one that is comprised of two or more words. Those words are usually connected by a hyphen. For example, in the sentence "The six-year-old boy tried to cross the street on his own," we have the compound adjective "six-year-old" modifying the noun "boy".

In the sentence "The attorney general has warned people that secondhand smoke is dangerous to their well-being," the compound adjective "secondhand" is modifying the noun smoke. Secondhand is an alternative spelling for "second-hand". it is comprised of two words put together to modify a noun or a pronoun. Another example would be:

Dad saved enough money to buy me a second-hand bike back then, and I couldn't have been happier.
