Instruction
Literary analysis has a characteristic sentence shape, and it is not the shape most students bring from middle school. Analysis constantly needs to hold two ideas in one breath: a claim and its consequence, an observation and its complication, a pattern and its exception. The punctuation mark built for exactly that job is the semicolon.
Start with the underlying grammar. An independent clause is a group of words with a subject and a verb that could stand alone as a sentence. Odysseus lies to the Cyclops. The lie saves his crew. Both are independent clauses. You have four ways to connect them, and they are not interchangeable.
- A period. Odysseus lies to the Cyclops. The lie saves his crew. Correct, but it presents the two facts as unrelated. The reader has to supply the connection.
- A comma plus a coordinating conjunction (and, but, or, nor, for, so, yet). Odysseus lies to the Cyclops, and the lie saves his crew. Correct, and it names the relationship — but only loosely.
- A semicolon. Odysseus lies to the Cyclops; the lie saves his crew. Correct, and it asserts that the two clauses belong together without spelling out how. The reader feels the causal link. This is the sentence of analysis.
- A comma alone. Odysseus lies to the Cyclops, the lie saves his crew. This is a comma splice, and it is an error. It is the single most common mechanical mistake in ninth-grade analytical writing.
Now add the refinement. A conjunctive adverb — however, therefore, moreover, nevertheless, consequently, indeed, instead, furthermore — names the logical relationship precisely. But a conjunctive adverb is not a conjunction. It cannot hold two independent clauses together on its own. It needs the semicolon in front of it and a comma after it:
Odysseus lies to the Cyclops; however, he cannot resist shouting his real name as he sails away.
Write that with a comma instead of a semicolon and you have a comma splice with an adverb in it. The test is mechanical and reliable: cover the connector. If what is on each side could stand alone as a sentence, you need a semicolon, not a comma.
The colon does a different job, and it is worth distinguishing now because you will need it in Unit 2. A semicolon balances two equal clauses. A colon announces that what follows will deliver on what came before — a list, an explanation, or a quotation. Odysseus’s flaw has a name: hubris.
One more rule that matters for essays specifically. When you introduce a quotation with a full independent clause, use a colon. When the quotation completes your own sentence grammatically, use no punctuation at all: Homer calls him a man “of many devices” from the first line. Over-punctuating quotations is the tell of a writer who has not yet learned to embed them.

Mentor sentences: the semicolon between equal clauses
Each sentence below is two independent clauses. Cover the connector and both halves could stand alone. Notice what the second clause does with the first: it restates it, extends it, or gives its cause. The reader feels that link without being told what it is.
He must be deformed somewhere; he gives a strong feeling of deformity, although I couldn’t specify the point.
Robert Louis Stevenson, The Strange Case of Dr. Jekyll and Mr. Hyde (1886), ch. 1, Enfield describing Hyde
It is the mark of a modest man to accept his friendly circle ready-made from the hands of opportunity; and that was the lawyer’s way.
Stevenson, Jekyll and Hyde, ch. 1, on Utterson
Sons are seldom as good men as their fathers; they are generally worse, not better; still, as you are not going to be either fool or coward henceforward, and are not entirely without some share of your father’s wise discernment, I look with hope upon your undertaking.
Homer, The Odyssey, tr. Samuel Butler (1900), bk. 2, Minerva to Telemachus
Reading the mentors. Enfield says Hyde “must be deformed somewhere,” and the clause after the semicolon supports it with his own evidence: the feeling of deformity with no point he can name. A period would leave two claims; the semicolon says the second is the first one, explained. In the Utterson sentence, the second clause is a verdict on the first (“that was the lawyer’s way”). Minerva’s sentence chains two semicolons, each clause sharpening the last (fathers, then worse sons, then “not better”), until the comma-and-still turn brings in the hope.
Mentor sentences: the semicolon plus a conjunctive adverb
Here the writer names the relationship. The pattern is always clause; adverb, clause: a semicolon before the adverb and a comma after it.
Ajax was wrecked, for Neptune drove him on to the great rocks of Gyrae; nevertheless, he let him get safe out of the water, and in spite of all Minerva’s hatred he would have escaped death, if he had not ruined himself by boasting.
Homer, The Odyssey, tr. Butler, bk. 4
I see no way out of it; nevertheless, we must try and find one.
Homer, The Odyssey, tr. Butler, bk. 10
there is a time for making speeches, and a time for going to bed; nevertheless, since you so desire, I will not refrain from telling you the still sadder tale of those of my comrades who did not fall fighting with the Trojans, but perished on their return, through the treachery of a wicked woman.
Homer, The Odyssey, tr. Butler, bk. 11, Ulysses to Alcinous
Reading the mentors. In the Ajax sentence, nevertheless turns the sentence: Neptune wrecks him; nevertheless, he lets him live; and only Ajax’s boasting finishes him. That is analysis in miniature. It holds a claim and its complication in one breath. Try the cover test on the middle sentence: “I see no way out of it” stands alone, and so does “we must try and find one,” so a comma before nevertheless would be a comma splice.
The test, one more time
Cover the connector. If both sides could stand alone as sentences, the join needs a semicolon (or a period, or a comma with and, but, or, nor, for, so, yet). A comma alone is a comma splice. A conjunctive adverb (however, therefore, moreover, nevertheless, consequently, indeed, instead, furthermore) never joins clauses by itself.
Worked key to the lab (SLS original)
The three pairs in the exercise.
- (a) Odysseus is clever; however, his cleverness is also what endangers him. Both halves stand alone, and the second reverses the first, so however names the turn. A period would present the danger as a separate fact. Semicolon before, comma after.
- (b) The suitors eat Odysseus’s herds; they are guests in his house. The second clause is the reason the first is an offense. No connector is needed, because the reader supplies the irony: guests are eating their host’s herds. A period would hide that the two facts are one fact.
- (c) Telemachus is young; he convenes an assembly of Ithaca’s elders. The contrast is felt without a word. If you want it stated, nevertheless is correct: Telemachus is young; nevertheless, he convenes an assembly of Ithaca’s elders.
Two more pairs, so the “five revised sentences” can be completed. (d) Ulysses tells the Cyclops his name is Noman. The other Cyclopes ignore his cries. Key: Ulysses tells the Cyclops his name is Noman; the other Cyclopes ignore his cries. The second clause is the result of the first. (e) Penelope has waited twenty years. She tests the stranger before she believes him. Key: Penelope has waited twenty years; nevertheless, she tests the stranger before she believes him. The adverb marks that her caution holds against her longing.
The check questions. Correct punctuation in the first quiz: Odysseus escapes the cave; however, he cannot resist naming himself. The false statement is false because “because he was proud” cannot stand alone, so a semicolon cannot attach it. In the fill-in, the first gap takes a semicolon (two equal clauses, the second explaining the first) and the second takes a colon (the words after it deliver the name of the technique).
Your explanation sentence. After each revision, say what the mark lets the reader see that a period would not. A model: “The semicolon in (b) makes the reader hear the second fact as the reason for the first.”
Formative check
Work through these before moving on. They are not graded — they tell you, and your teacher, whether the standard below has landed yet.
Which sentence is punctuated correctly?
A semicolon can be used to attach a dependent clause, such as “because he was proud”, to a main clause.
Homer never states that pride is dangerous he dramatises it, and the technique has a name showing rather than telling.
Rewrite these three choppy pairs as single analytical sentences, using a semicolon in at least two of them and a conjunctive adverb in at least one. (a) Odysseus is clever. His cleverness is also what endangers him. (b) The suitors eat Odysseus’s herds. They are guests in his house. (c) Telemachus is young. He convenes an assembly of Ithaca’s elders. After each, add one sentence explaining what the punctuation choice makes the reader see that a period would not.
How confident are you that you can test any sentence for a comma splice by covering the connector and checking whether both sides could stand alone?
The Odyssey, Books 1-8
The Odyssey, Books 1-8 so far Bridge summary — not the primary text
A recap of what you have already read, written for this course, so the reading check below does not require re-opening every earlier popover.
Homer withholds Odysseus for four books while Telemachus fails to move the suitors and sets out for news of his father (Books 1-4). Odysseus himself finally appears leaving Calypso’s island, surviving a shipwreck, and washing up on Scheria, where Nausicaa and her family give him the hospitality the suitors deny Telemachus (Books 5-8). By the end of Book 8 he has been fed, clothed, entertained and promised a ship home, and is just about to tell his hosts — and the reader — who he is.
