in the sentence "Tarao loaded the groceries into the cart." Is the clause adjectival, adverbial, or noun?

The only clause is the entire sentence -- which of course is an independent clause.

Adjectival, adverbial, and noun clauses are all dependent clauses.

Ohhh, okay! Thank you very much! =]

You're welcome.

To determine whether the clause in the sentence "Tarao loaded the groceries into the cart." is adjectival, adverbial, or noun, we need to identify the type of clause.

In this case, the clause "loaded the groceries into the cart" is a verb phrase functioning as the predicate of the sentence, describing the action Tarao performed. It does not function as a noun, as it doesn't serve as the subject or object of the sentence.

Therefore, the clause in question is adverbial because it modifies the verb "loaded" by providing information about how Tarao performed the action. Specifically, it indicates the direction or destination of the action, answering the question "where?"
