A student writes: 'She was tired, and hungry.' Is the comma correct?
AYes — a comma always comes before 'and'
BYes — the sentence has two ideas, so a comma is needed
CNo — a comma before a coordinating conjunction is only needed when it joins two independent clauses; 'hungry' alone is not a clause
DNo — 'and' never takes a comma under any circumstances
The comma rule hinges on what the conjunction is joining. 'She was tired and hungry' joins two adjectives — not two independent clauses — so no comma is needed. A comma before a coordinating conjunction is required only when each side can stand alone as a complete sentence (has its own subject and verb). 'Hungry' has neither; it's a single adjective.
Question 2 Multiple Choice
What does 'yet' signal in this sentence: 'She practiced every day, yet she still struggled in the recital'?
AAddition — it means 'and also'
BResult — her practicing caused the struggle
CContrast with surprise — she practiced and expected to improve, but didn't
DCause — it explains why she struggled
'Yet' is not a synonym for 'but.' Both introduce contrast, but 'yet' carries an additional sense of surprise or contradiction against expectation. She practiced every day and would reasonably expect to improve — 'yet' signals that the expected outcome was violated. 'But' would state a simple contrast; 'yet' adds the feeling of unexpectedness.
Question 3 True / False
A comma is required before nearly every coordinating conjunction.
TTrue
FFalse
Answer: False
A comma before a coordinating conjunction (FANBOYS) is only required when the conjunction joins two independent clauses — meaning both sides have a subject and verb and could stand alone as sentences. When a conjunction joins two words ('bread and butter'), two phrases ('tired but happy'), or any non-clause elements, no comma is needed.
Question 4 True / False
The acronym FANBOYS stands for: for, and, nor, but, or, yet, so — the seven coordinating conjunctions in English.
TTrue
FFalse
Answer: True
FANBOYS is a reliable mnemonic because there are exactly seven coordinating conjunctions and the acronym captures all of them. Each carries a distinct logical meaning: 'for' (reason), 'and' (addition), 'nor' (negative addition), 'but' (contrast), 'or' (alternative), 'yet' (surprised contrast), 'so' (result).
Question 5 Short Answer
How do you decide whether to put a comma before a coordinating conjunction? State the rule and give one example where a comma is needed and one where it is not.
Think about your answer, then reveal below.
Model answer: Use a comma before a coordinating conjunction when it joins two independent clauses — both sides must have a subject and a verb and be able to stand alone as sentences. Example with comma: 'She studied all night, but she still failed.' Example without comma: 'She studied hard but failed.' The test is: can each part stand alone? If both can, use a comma. If one side is just a word or phrase, skip it.
The comma is not about the conjunction itself — it's about the grammatical weight of what the conjunction is joining. Two full clauses = comma. Words or phrases = no comma. A quick test is to cover each side of the conjunction and ask 'is this a complete sentence?' If both answers are yes, a comma belongs before the conjunction.
