1. Phrases vs Clauses - The Basic Difference
Phrase: A group of words that makes some sense but NOT complete sense. Does NOT contain a subject and predicate combination.
Clause: A group of words that contains BOTH a subject and a predicate. Can be independent (main) or dependent (subordinate).
| Type | Definition | Example | Key Test |
|---|---|---|---|
| Phrase | Group of words without subject-verb combination | in the morning a blue car walking slowly |
Cannot stand alone as a sentence |
| Clause | Group of words with subject AND verb | when I was young because she was tired the book that I read |
Has subject doing/being something |
| Main/Independent Clause | Can stand alone as complete sentence | She completed her homework. The sun was shining brightly. |
Complete thought, independent |
| Subordinate/Dependent Clause | Cannot stand alone, depends on main clause | when she finished her homework because the sun was shining |
Incomplete thought, needs main clause |

🎯 Phrases & Clauses Challenge
Identify whether the underlined group of words is a phrase or clause, and what type.
1. The girl with blue eyes is my sister.
Reason: No subject-verb pair. Modifies the noun 'girl'.
2. I know what you want.
Reason: Has subject 'you' and verb 'want'. Acts as object of 'know'.
3. She left when the meeting ended.
Reason: Has subject 'meeting' and verb 'ended'. Answers 'when did she leave?'
4. The book that I borrowed is interesting.
Reason: Has subject 'I' and verb 'borrowed'. Modifies the noun 'book'.
5. Walking in the park is refreshing.
Reason: No finite verb. 'Walking' is a gerund, not a finite verb.
8. Memory Aids & Common Errors
Quick Tests:
• Phrase Test: Does it have a subject doing/being something? NO → Phrase
• Clause Test: Does it have subject+verb? YES → Clause
• Noun Clause Test: Can you replace it with 'it' or 'something'?
• Adjective Clause Test: Does it answer 'which one?' or 'what kind of?'
• Adverb Clause Test: Does it answer when, where, why, how, or under what condition?
Common Errors:
1. Comma with Adjective Clauses: Non-defining needs commas, defining doesn't

The boy who won the prize is my friend. (defining)
2. That vs Which: 'That' for defining clauses, 'Which' for non-defining
3. Dangling Modifiers: Phrases must clearly modify the right noun
Incorrect: Running down the street, the bus left. (Who was running?)
