(I don't know all of the abbreviations you're using.)

In the sentence "The cat is on the roof," the sentence pattern is SVA (Subject-Verb-Adverbial).

Here's a breakdown:
- Subject: "The cat"
- Verb: "is"
- Adverbial: "on the roof"

The sentence uses the linking verb "is" to connect the subject "The cat" to the adverbial "on the roof." This sentence pattern is commonly used to describe a location or state of being.

Now, let's analyze the second example: "We painted the wall green."

The sentence pattern used here is SVO (Subject-Verb-Object).

Here's the breakdown:
- Subject: "We"
- Verb: "painted"
- Object: "the wall"
- Object Complement: "green"

The subject "We" carries out the action expressed by the verb "painted" on the object "the wall" and adds an object complement "green" to describe the result of the action. This sentence pattern is commonly used for describing actions performed on objects.

To determine the sentence pattern, we need to identify the subject (S), verb (V), and complement (C) or object (O) in each sentence.

1. "The cat is on the roof."

In this sentence, the subject is "The cat," the verb is "is," and the complement is "on the roof." The sentence pattern is Subject + Verb + Complement (SVC).

The verb "is" is a linking verb that connects the subject "The cat" with the complement "on the roof."

2. "We painted the wall green."

In this sentence, the subject is "We," the verb is "painted," and the object is "the wall green." The sentence pattern is Subject + Verb + Object (SVO).

The verb "painted" is a transitive verb that requires an object, which is "the wall green."

In summary:
1. "The cat is on the roof." - SVC sentence pattern because it has a subject ("The cat"), a linking verb ("is"), and a complement ("on the roof").
2. "We painted the wall green." - SVO sentence pattern because it has a subject ("We"), a transitive verb ("painted"), and an object ("the wall green").
