There is good reason to be thankful.what is the sentence pattern.

The introductory "there" is not the subject; "reason" is. So which comes first in word order in this sentence?

To determine the sentence pattern, we'll analyze the structure of the given sentence:

"There is good reason to be thankful."

In this sentence, the subject is "there" (it serves as a placeholder subject), the verb is "is," and the predicate complement is "good reason to be thankful." The phrase "good reason" acts as the subject complement, while the infinitive phrase "to be thankful" functions as an adverbial phrase modifying the predicate complement.

Therefore, the sentence pattern can be described as follows:

Subject (there) + Verb (is) + Predicate Complement (good reason to be thankful)
