1. Diagramming Begins! What is diagramming? Sentence analysis
Shows relationship of each word to the rest of the sentence
Think of frog dissection

2. First… We already know:
Every sentence MUST have a subject and verb
Subject=noun
Verb=words of doing or being
Start by asking: WHO or WHAT is DOING or BEING something?
Now, draw a horizontal line and divide it with a vertical one:

3. Next…
Place the subject (noun) and all the things that go with it on the left side
Place the predicate (main verb) and all things that go with it on the right side
Subject Predicate

4. See how this basic sentence is diagrammed:
Rex barks.
Rex Barks
Subject Predicate
Who or what? Does or is what?

5. Now You Try: Rex whined. Subject Predicate
Who or what? Does or is what?

6. (Hint: be sure to include all parts of the verb.)
Good. Now Try again:
Rex was panting.
(Hint: be sure to include all parts of the verb.)
Subject Predicate
Who or what? Does or is what?

7. Rex might have been scratching.
Diagram these sentences. Remember, subject on the left, predicate on the right.
Rex might have been scratching.
Rex did bark.
Subject Predicate
Who or what? Does or is what?

8. Rex could have been growling.
Diagram these sentences. Remember, subject on the left, predicate on the right.
Rex should have howled.
Rex could have been growling.
Subject Predicate
Does or is what?

9. Rex must have run. Rex had slept.
Diagram these sentences. Remember, subject on the left, predicate on the right.
Rex must have run.
Rex had slept.

10. Diagram these sentences.
Rex may be eating.
Rex will have been digging.

11. What Have We Learned So Far?
SOMEBODY DOES or IS Or SOMETHING SOMETHING

12. Now, what if we want to make our sentences pretty?
birds sing What if we want to know: Which ones? Where? What kinds? When? Whose? Why? How many? How?

13. Since ADJECTIVES
Answer the ADJECTIVE QUESTIONS about NOUNS, they are diagrammed on slanting lines under the noun they modify: birds sing How many birds? Three = ADJ
three

14. Now notice this sentence:
Those three blue birds sing. Same subject and verb, birds sing But the noun is modified by three words that answer three different ADJECTIVE QUESTIONS.
blue
Those
three

15. The birds sing sorrowfully.
How about this?
The birds sing sorrowfully.

16. Good:
Sorrowfully answers the ADVERB QUESTION: HOW? birds sing So, words that answer ADVERB QUESTIONS are placed on a slanted line under the VERB
the
sorrowfully

17. Notice that,
While an adjective usually goes in front of its noun, an adverb can hop about in the sentence:
Sorrowfully the birds sing.
The birds sorrowfully sing.
The birds sing sorrowfully.
All three sentences are diagrammed in exactly the same way.

18. Diagram these sentences
Diagram these sentences. Put adjectives under nouns, adverbs under verbs. Write what question each modifier answers.
Poor Rex whined pitifully.
That tired Rex was panting furiously.
Yesterday Rex might have been scratching.
Rex did really bark.
Why did Rex really bark?
Why should that naughty Rex have howled so dismally?

19. Ah-ha! A few tricks:
#5, the question—turn it into a declarative sentence…it will be diagrammed the same as #4.
#6— “why” doesn’t answer an adverb question; it is an adverb question. Diagram it just as you would an adverb.
#6—Where did you put “so”? That was really sneaky! It answers the ADVERB QUESTION: HOW. But is does not modify the verb “howled.” (How did he howl? So? No.) No, it answers the question “how” about “dismally.” (How dismally? So dismally.) Remember that adverbs modify verbs, adjectives and other adverbs.)

20. So…
Rex should have howled
that
naughty
dismally
why so

21. What have we learned so far?
Review and Practice:
What have we learned so far?
In a sentence, somebody or something does or is something.
An adjective answers the questions
Which one
What kind
Whose
How many
An adverb answers the questions
Where
When
Why
How

22. Harry has been listening carefully.
Diagram these sentences. Be sure to find all helping verbs, and be careful that each modifier is attached to the word it modifies.
Harry has been listening carefully.
Harry has not been listening carefully. (Hint: “not” answers how Harry listens.)

23. Lucy’s blue sweater was thrown downstairs.
Diagram these sentences. Be sure to find all helping verbs, and be careful that each modifier is attached to the word it modifies.
Lucy’s blue sweater was thrown downstairs.
That sweet old lady might have been sleeping there.

24. Suddenly the booming thunder echoed hollowly.
Diagram these sentences. Be sure to find all helping verbs, and be careful that each modifier is attached to the word it modifies.
Suddenly the booming thunder echoed hollowly.
The big bad wolf huffed importantly.

25. That child might be crying now. How they must have been laughing!
Diagram these sentences. Be sure to find all helping verbs, and be careful that each modifier is attached to the word it modifies.
That child might be crying now.
How they must have been laughing!

26. ** More practice for homework!
Diagram these sentences. Be sure to find all helping verbs, and be careful that each modifier is attached to the word it modifies.
Away flew the silly geese. (Careful! What IS the verb? What or who DID the verb?)
My sister may play here.
** More practice for homework!

27. And Now: Diagramming Prepositional Phrases
Review: what is a prepositional phrase? What part(s) of speech are associated with a prepositional phrase?
Identify the prepositional phrase(s) in this sentence:
The squirrel ran up the tree, down the tree, behind the tree, through the tree, under the tree, around the tree and into the tree.

28. Notice:
The squirrel ran up the tree, down the tree, behind the tree, through the tree, under the tree, around the tree and into the tree. All the underlined words connect a noun, “tree,” with the rest of the sentence, in this case through the verb “ran.” Notice that each propositional phrase (“phrase” means the preposition, its object (the noun it connects) and any modifiers of the object)) answers the questions “where” or possibly “how.” These are our old friends, the ADVERB QUESTIONS, and since the phrase answers where and how the verb was carried out, we know these phrases are acting as ADVERBS modifying the verb.

29. How to diagram a prepositional phrase:up
tree
the
Notice that the preposition goes on a slanting line just below the word the phrase modified, the object goes on a horizontal line connected to the preposition line, and any modifier of the noun object goes under it. In these phrases the word “the” is an adjective telling “which tree.” Even though our word order goes: preposition, adjective, noun object, we diagram it: preposition, noun object, adjective, because we are showing the importance of words.

30. It’s pretty, no? You too, can have this much linear fun!
squirrel

It’s pretty, no? You too, can have this much linear fun!

31. Let’s diagram these prepositional phrases used as ADJECTIVES:
The boy with the red hat was singing.
A basket of food appeared.
That cat of Lucy’s scratches.
An amount of six dollars was owed.

32. Now, a trick:
Diagram this sentence: The bird in the tree sang happily. **Remember to figure out which question is being asked!**

33. Okay, so, you found the prepositional phrase
Okay, so, you found the prepositional phrase. You asked, “What question does it answer?” and you said “Where,” didn’t you? What the prepositional phrase “in the tree” really tells is “which one.” It does this by telling “where.” Now think about that. We often tell “which one” about a noun in this way. “Which dress will you wear?” “The one on the bed.” This is an example of how you must always THINK about what words and word groups are really doing. In most cases, word order will be a clue as to what a prepositional phrase modifies.

34. It may be well to notice that, in our speech patterns, while one-word adjectives generally go in front of the nouns they modify, prepositional phrases used as adjectives go after their nouns. The big bad wolf; the bottle (of milk).

35. A final example to study:
The horse with the star on its forehead galloped through the pasture with angry snortings at its pursuers.

36. The horse with the star on its forehead galloped through the pasture with angry snortings at its pursuers.
horse
galloped
the
with
with
snortings
star
through
pastures at
angry
pursuers
the on
the
forehead
its
its
Study the placement of all phrases. Notice “on its forehead” modifies the noun “star.” (“On its forehead” does NOT describe this horse!) Nor did it “gallop” “at its pursuers.” that tells about its “snortings.” Any noun, not just the sujbect noun, may be modified by a prepositional phrase.

37. Review and Practice
Each word in a sentence is one of the eight parts of speech, depending on the job it does in the sentence.
Groups of words, called phrase, may act as single parts of speech.
A prepositional phrase consists of a preposition, a noun object, and perhaps some adjectives modifying the object.
A preposition connects the object with the rest of the sentence and show the object is related to the sentence. Usually the relationship has to do with direction, space, time, possession, etc.
Prepositional phrases usually act as ADJECTIVES or ADVERBS. The whole phrase will answer one of the ADJECTIVE or ADVERB questions.
We diagram a prepositional phrase under the word it modifies. The object goes on a horizontal line connected to the preposition. Any modifiers of the object go under the object.

38. The lamp with the crooked shade leaned against the wall.
Diagram these sentences after you have found each prepositional phrase and asked yourself, “What question does it answer?”
The lamp with the crooked shade leaned against the wall.
The carefree moth with the black spots o nits wings lunged happily toward the flames of the sooty lantern.

39. The rich society lady sighed with regret over the column in the paper.
Diagram these sentences after you have found each prepositional phrase and asked yourself, “What question does it answer?”
The rich society lady sighed with regret over the column in the paper.
After the rain Nellie splashed in the puddles on the walk.

40. Suzy has been playing with that girl in the house at the corner.
Diagram these sentences after you have found each prepositional phrase and asked yourself, “What question does it answer?”
John had been reading about space travel in that book with the orange cover.
Suzy has been playing with that girl in the house at the corner.

41. During the winter the farmer worked at repairs in his barn.
Diagram these sentences after you have found each prepositional phrase and asked yourself, “What question does it answer?”
During the winter the farmer worked at repairs in his barn.
Harry should not have been sleeping on the porch without a blanket.

42. In January I walk to school in the dark.
Diagram these sentences after you have found each prepositional phrase and asked yourself, “What question does it answer?”
In January I walk to school in the dark.
Beside the dry book she wept for the thirsty violets.

43. Coordinating Conjunctions
Luckily, you already know what a conjunction is. So, get out your notes! What two kinds of conjunctions are there? What is a coordinating conjunction? What are some examples of coordinating conjunctions?

44. COMPOUND ELEMENTS
When two or more items are joined by a coordinating conjunction, they form a COMPOUND ELEMENT. Here are some examples of how these things are diagrammed:
RUTH
RAN
AND
ANN
EXAMPLE SENTENCE WITH COMPOUND SUBJECTS: RUTH AND ANN

45. EXAMPLE SENTENCE WITH COMPOUND VERBS

51. UNDERSTOOD “YOU”
So far, you have always, it is hoped, found the subject of each verb. In every sentence, the “doer” or “be-er” of the verb has been stated. However, what about this sentence?
Go!
If a large, fierce person says this to you, you will not stick around looking for a subject. You are immediately aware that the doer of the action is supposed to be “you.” That is quickly understood.

52. UNDERSTOOD “YOU”, CONT.
In fact, we call the subject of a command the “understood ‘you’” and we diagram it thus:
(YOU) GO
Other Examples:
*Let me alone.
*Give me my purse.
*March!

53. DIRECT ADDRESS
Until now, the only NOUN JOBS you have studied are SUBJECT and OBJECT OF A PREPOSITION. There are many more. Now you may add DIRECT ADDRESS. Here are some examples:
Mary, the flowers are blooming.
Come here, John.
You realize, Harry, that I know the truth.

54. DIRECT ADDRESS, CONT.
When we call someone by name in a sentence, we are using a NOUN in DIRECT ADDRESS.
This is how such nouns are diagrammed:
MARY
FLOWERS
ARE BLOOMING
THE
The NOUN of DIRECT ADDRESS has no grammatical connection with the sentence, so it sits on a line above the main clause of the sentence.

55. INTERJECTIONS!
An interjection merely expresses emotion; it does no grammatical job in the sentence, so it sits on a line above the sentence, thus:
WOW!
BOB
FELL
DOWN
STAIRS
THE

56. INTRODUCTORY WORDS
Like nouns of direct address and interjections, certain INTRODUCTORY WORDS have no grammatical connection with the sentence and are diagrammed on a line above the subject:
NOW, YOU TRY:
YES, I STAYED.
WELL, REX WAS BARKING.
YET, I COULD NOT REMEMBER. NO HE
LEFT

57. CELEBRATE!
Now you have finished all the basic steps to beginning diagramming. Some basics to remember:
Make sure you have found all parts of the verbs, all helpers
Pick out prepositional phrases. Determine what question (adjective or adverb) they answer.
Check to make sure your diagram makes sense. Is your subject the “doer” or the “be-er” of the verb? Does each modifier answer its question about the word to which you have it attached?

58. NOW, A LITTLE PRACTICE:
The wily fox jumped from the stump of the oak tree.
Quickly he ran across the sunlit clearing and into the dark forest.
Over the river and through the woods to grandmother’s house we go.
On the ninth page of the little diary in her bureau drawer was written the secret of the missing scarf.
Should you have been tapdancing on her new table or singing so loudly?
