Word Class Classification Code worksheet for grammar practice, featuring a code table and sentences to identify word types.

Let’s go step by step to figure out the word class for each underlined word in the sentences. We’ll use the code table at the top:

- noun = 1
- verb = 2
- adjective = 3
- adverb = 4
- preposition = 5
- co-ordinating conjunction = 6
- subordinating conjunction = 7
- determiner = 8
- pronoun = 9
- possessive pronoun = 10
- relative pronoun = 11
- modal verb = 12

We already have one done for us: “turbulent” is an adjective → 3.

Sentence 1:
> The turbulent waves crashed heavily against the rocky shore while gulls squawked noisily.

Underlined words: heavily, against, while, noisily

- heavily → describes *how* they crashed → that’s an adverb → 4
- against → shows relationship between “crashed” and “shore” → preposition → 5
- while → connects two clauses (“waves crashed...” and “gulls squawked...”) and shows time → subordinating conjunction → 7
- noisily → describes *how* gulls squawked → adverb → 4

So boxes for sentence 1: 4, 5, 7, 4

Sentence 2:
> This horror film is terrifying and it lasts for three hours!

Underlined words: This, terrifying, and, it, for

- This → points to a specific film → determiner → 8
- terrifying → describes the film → adjective → 3
- and → joins two ideas (“film is terrifying” + “it lasts...”) → co-ordinating conjunction → 6
- it → replaces “this horror film” → pronoun → 9
- for → shows duration (“lasts for three hours”) → preposition → 5

Boxes for sentence 2: 8, 3, 6, 9, 5

Sentence 3:
> She shouldn’t be in trouble because those slimy frogs weren’t hers!

Underlined words: She, shouldn’t, because, those, hers

- She → subject of the sentence → pronoun → 9
- shouldn’t → short for “should not” → “should” is a modal verb → 12
- because → explains why → introduces reason → subordinating conjunction → 7
- those → points to specific frogs → determiner → 8
- hers → means “belonging to her” → possessive pronoun → 10

Boxes for sentence 3: 9, 12, 7, 8, 10

---

Sentence 4:
> After several seconds, an enormous bang erupted, which alarmed everyone.

Underlined words: After, several, an, which

- After → shows time relationship → preposition → 5
- several → tells how many seconds → determiner → 8
- an → before “enormous bang” → article → determiner → 8
- which → refers back to “bang” and adds extra info → relative pronoun → 11

Boxes for sentence 4: 5, 8, 8, 11

Final Answer:
1. 4, 5, 7, 4
2. 8, 3, 6, 9, 5
3. 9, 12, 7, 8, 10
4. 5, 8, 8, 11
