This video's purpose is to help you make a syntactic tree diagram of the sentence of "The big red foxes are ruining my garden".
Today, our topic is Syntactic Tree Diagrams. In order to fully understand english sentence organization, we use tree diagrams. While we are drawing trees, we split the sentence into two parts: subject and the predicate.
First, lets focus on the subject. `The fox` can be the subject of a sentence and it is also a noun phrase. While drawing the tree, we split this noun phrase into 2 branches. `The` is our determiner and `fox` is our noun. \
Plural -s is another linguistic feature that we need to pay attention while drawing tree diagrams. Here, our subject is pluralized. Plural -s is considered as a part of the subject thats why we draw its branch from the noun phrase.
Lets add an adjective to spice things up. Adjectives are words that we use to modify and describe nouns. For example `big`. Big is our adjective and a noun with an adjective is called adjective phrase. Adjective phrases have their own branches under noun phrases. Therefore, we draw the adjective `big` under the adjective phrase which is located under the noun phrase.
As you all know adjectives are located right behind nouns to modify them within the noun phrase. But what will happen if we add one more adjective into a noun phrase that already has one? Well, its pretty easy. Since we have more than one adjective we need to add an extra adjective phrase branch under the noun phrase and we keep the rest of the tree the same.
Now lets examine this noun phrase in a sentence. As we said before, `big red foxes` which is our noun phrase is the subject of our sentence. In order to form a sentence we add our predicate which is `are ruining my garden`. Divide the sentence into 2 sections: subject and the predicate. We have already reviewed the subject part.
For the predicate part, we always write it down in 2 sections: first one is auxiliary and the second one is verb phrase. The auxiliary will define our sentence's time aspect. For this sentence, it is present progressive aspect. Write the time aspect under the tense and the b+ing is under the progressive aspect. The rest of the sentence should be written under the verb phrase section. Our verb phrase consists of a verb and a noun phrase. `ruin` is the verb and `my garden` is our noun phrase. This time we only have a determiner which is `my` and our core noun is `garden`.
