Question

What is/are the noun(s) in the following sentence?: We tried shipping the package to the customer.

Answer 1

package and customer

Explanation:

"Try" a verb needs a gerund form ship to shipping.
Gerund is always a noun.

But shipping here functions as an adjective by a grammar rule that modifies to package.
Package is a direct object here. a noun
customer is an indirect object, another noun.

Rule is---Sub+ Verb+ direct object+preposition+ indirect object.
