Diagramming Sentences Worksheets - 15 Worksheets Library - Free Printable

Let’s go through each sentence one by one. We’ll find the subject (who or what the sentence is about) and the verb (what the subject is doing). Then we’ll label any other parts:
- N = noun (a person, place, thing, or idea)
- P = pronoun (like he, she, it, they — replaces a noun)
- A = article (like “a,” “an,” or “the”)
- ADJ = adjective (describes a noun)
- ADV = adverb (describes a verb, adjective, or another adverb — often ends in -ly)

We’ll draw a line between subject and verb like this:
Subject | Verb

---

1. John called loudly.
→ Subject: John (person doing the action)
→ Verb: called (what John did)
→ “loudly” tells *how* he called → that’s an adverb (ADV)

Answer:
John | called
loudly → ADV

---

2. He watched a long program.
→ Subject: He (pronoun for a person)
→ Verb: watched (what he did)
→ “a” = article (A)
→ “long” describes “program” → adjective (ADJ)
→ “program” = noun (N)

Answer:
He | watched
a → A
long → ADJ
program → N

3. The rain was heavy.
→ Subject: rain (thing the sentence is about)
→ Verb: was (linking verb — connects subject to description)
→ “The” = article (A)
→ “heavy” describes “rain” → adjective (ADJ)

Answer:
rain | was
The → A
heavy → ADJ

*(Note: Sometimes “was” is considered part of the verb phrase with “heavy,” but here we treat “was” as the main verb since it links subject to description.)*

4. Kevin ate a big sandwich.
→ Subject: Kevin
→ Verb: ate
→ “a” = article (A)
→ “big” describes “sandwich” → adjective (ADJ)
→ “sandwich” = noun (N)

Answer:
Kevin | ate
a → A
big → ADJ
sandwich → N

5. Martin reads long books.
→ Subject: Martin
→ Verb: reads
→ “long” describes “books” → adjective (ADJ)
→ “books” = noun (N)

Answer:
Martin | reads
long → ADJ
books → N

---

6. We obey our parents.
→ Subject: We (pronoun)
→ Verb: obey
→ “our” shows possession → still functions like an adjective (ADJ) because it describes “parents”
→ “parents” = noun (N)

Answer:
We | obey
our → ADJ
parents → N

*(Some might argue “our” is a possessive pronoun, but in diagramming at this level, it’s often labeled as ADJ since it modifies a noun.)*

7. Quentin wrote quickly.
→ Subject: Quentin
→ Verb: wrote
→ “quickly” tells *how* he wrote → adverb (ADV)

Answer:
Quentin | wrote
quickly → ADV

8. This seat is my favorite.
→ Subject: seat (the thing being described)
→ Verb: is (linking verb)
→ “This” points to which seat → acts like an adjective (ADJ)
→ “my” shows possession → also acts like an adjective (ADJ)
→ “favorite” is describing the seat → adjective (ADJ) — though sometimes treated as a noun, here it’s functioning as an adjective meaning “most liked”

Wait — let’s think again. In “This seat is my favorite,” “favorite” is actually standing in for “favorite thing” — so it’s acting as a noun here. But in many school diagrams, especially at this level, “favorite” after “is” is labeled as an adjective.

Actually, let’s check standard practice:
In “This seat is my favorite,” “favorite” is a predicate nominative — it renames the subject. So it should be labeled as a noun (N).

But wait — “my favorite” together? “My” is possessive pronoun → ADJ, “favorite” is noun → N.

Alternatively, some curricula simplify and call “favorite” an adjective here. To match the example given (“Joan | called her friend.” where “her” is likely labeled as ADJ or P), let’s follow common elementary labeling:

→ “This” → ADJ (modifies “seat”)
→ “seat” → N (but it’s the subject, so we don’t relabel it separately unless asked)
→ “is” → verb
→ “my” → ADJ (possessive adjective)
→ “favorite” → N (because it’s the thing being equated to “seat”)

But looking back at the instructions: “Identify any other nouns (N), pronouns (P), articles (A), adjectives (ADJ) or adverbs (ADV).”

So for sentence 8:

Subject: seat
Verb: is
Other words:
“This” → ADJ
“my” → ADJ (or P? “my” is a possessive pronoun, but often taught as ADJ in early grades)
“favorite” → N (since it’s the complement renaming “seat”)

However, to keep it simple and consistent with typical worksheet answers, many teachers would label:

“This” → ADJ
“my” → ADJ
“favorite” → ADJ (even though technically it’s a noun here — but in context, it’s describing the seat’s quality)

Hmm. Let’s look at the example again:
“Joan | called her friend.”
They didn’t label “her” or “friend” in the example output shown — wait, actually in the image, above the example it says:
“A N” over “her friend”? No — looking at the original image text:
It says:
EXAMPLE: Joan | called her friend.
And above “her friend” it has “A N”? Wait no — in the user’s image transcription, it says:
“EXAMPLE: Joan | called her friend.” and then above “her friend” it has “A N”? Actually, in the OCR it says:
“A N” — probably meaning “her” = A? That doesn’t make sense.

Wait — re-reading the user’s provided text:
“EXAMPLE: Joan | called her friend.”
Then it says: “A N” — likely positioned above “her” and “friend”. But “her” is not an article. Probably a typo or mislabel in the example.

Given confusion, let’s stick to standard grammar:

For sentence 8:
“This seat is my favorite.”
- Subject: seat
- Verb: is
- “This” → demonstrative adjective → ADJ
- “my” → possessive pronoun → can be labeled P or ADJ; in most elementary worksheets, it’s ADJ
- “favorite” → in this case, it’s a noun (short for “favorite one”) → N

But to avoid overcomplicating, and since the worksheet likely expects simple labels, I’ll go with:

seat | is
This → ADJ
my → ADJ
favorite → ADJ *(common simplification in schools)*

Actually, let me double-check with reliable sources: In “This is my favorite,” “favorite” is a predicate nominative → noun. But in “This seat is my favorite,” same thing.

However, for consistency with how such worksheets are usually graded, and since the instruction says “identify any other nouns...”, and “favorite” is functioning as a noun here, I’ll label it N.

Final decision for #8:
seat | is
This → ADJ
my → ADJ (or P — but let’s use ADJ as it’s modifying “favorite”)
favorite → N

But “my” is a pronoun! Possessive pronoun. So perhaps:

“my” → P
“favorite” → N

Yes, that’s more accurate.

So revised:

seat | is
This → ADJ
my → P
favorite → N

Okay, let’s finalize all answers now.

Final Answers:

1. John | called
loudly → ADV

2. He | watched
a → A
long → ADJ
program → N

3. rain | was
The → A
heavy → ADJ

4. Kevin | ate
a → A
big → ADJ
sandwich → N

5. Martin | reads
long → ADJ
books → N

6. We | obey
our → ADJ (or P — but commonly ADJ in worksheets)
parents → N
*(Let’s use ADJ for “our” to match typical elementary labeling)*

7. Quentin | wrote
quickly → ADV

8. seat | is
This → ADJ
my → P
favorite → N

Wait — for #6, “our” is a possessive pronoun, so it should be P. Similarly in #8, “my” is P.

Let’s correct:

6. We | obey
our → P
parents → N

8. seat | is
This → ADJ
my → P
favorite → N

Yes.

Now compiling final answer cleanly.
