Worf's Klingon Quotes: Honor, Battle, and Heartbreak in TNG and DS9
Worf's Klingon Quotes: Honor, Battle, and Heartbreak in TNG and DS9
Lieutenant Commander Worf, son of Mogh, is the most-quoted Klingon in Star Trek — and the only major character who routinely uses Klingon-language phrases on screen. This article collects his most memorable Klingon lines, with the Klingon original, English translation, and the episode they came from.
A note: most of Worf's speech is in English. The Klingon-language moments are deliberate punctuation — they appear when the writers want to mark a moment as culturally Klingon rather than Federation. They carry weight precisely because they are rare.
On Battle and Death
Heghlu'meH QaQ jajvam.
"Today is a good day to die."
Worf invokes this line multiple times across TNG and DS9 — before boarding actions, before duels, before the Dominion War's final assaults. The phrase predates him in Klingon culture and is often attributed to Kahless the Unforgettable. Grammatically: Hegh-lu'-meH is a purpose clause with an indefinite subject ("for one to die"), QaQ is the stative verb "good," and jajvam is "this day."
qaStaHvIS wa' ram, loS SaD Hugh SIjlaH qetbogh loD.
"In one night, a running man can slit four thousand throats."
A Klingon proverb Worf quotes to Wesley Crusher in TNG. The grammar is dense: qaStaHvIS is the time-clause "while it occurs," SIjlaH is "is able to slit," and qetbogh is a participle "who runs."
bIjatlh 'e' yImev. yIQu'!
"Stop talking. Do your duty!"
Worf in DS9, multiple episodes, usually to junior officers stalling under fire. Qu' is duty — one of the most freighted nouns in the Klingon lexicon.
On Honor
batlh bIHeghjaj.
"May you die well."
A Klingon farewell delivered to a respected enemy or an honored friend going into danger. batlh is the foundational concept of honor in Klingon culture; bIHeghjaj is "may you die." See our full vocabulary of honor for the supporting terminology.
Heghlu'DI' mobbe'lu'chugh QaQpu' Hegh wanI'.
"Death is an experience best shared."
A Klingon proverb Worf cites in multiple TNG episodes. The implication: dying with comrades is better than dying alone, which is also why Klingons place such importance on the death scream and on having someone present to witness the moment of death.
Heghlu'meH QaQ Daghor.
"You spoil a perfectly good day to die."
Worf to Riker, gently mocking his commanding officer's Federation tendency to choose negotiation over combat. Affectionate, sharp-edged.
On Loss — The K'Ehleyr Sequence
In TNG "Reunion," K'Ehleyr — Worf's mate and the mother of his son Alexander — is murdered by Duras. The scene at her bedside is the most emotionally heavy Klingon-language moment in Star Trek.
The Death Scream
Worf opens K'Ehleyr's eyes, tilts his head back, and roars. The Klingon tradition is to scream into the sky to warn the afterlife: a warrior is coming. Be ready. The scream is not grief — grief is reserved for the dishonored dead. It is a warning to Sto-vo-kor.
tlhIngan jIH. tlhIngan SoH.
"I am a Klingon. You are a Klingon."
Worf to his son Alexander, multiple episodes, asserting identity against Alexander's wish to be raised human.
The Wedding — Worf and Jadzia (DS9 "You Are Cordially Invited")
The wedding ceremony recites the legend of Kahless and Lukara — how they held the Great Hall of Qam-Chee against 500 of Molor's warriors and afterward made love for twelve days.
tlhIngan jIH! tlhIngan SoH! maSuv!
"I am a Klingon! You are a Klingon! We fight!"
The ceremonial declaration during the marriage ritual. The bride must affirm her warrior nature; the groom must affirm his. Sirella, Martok's wife, presides.
For more on the wedding ceremony, see Klingon wedding vows and phrases.
On Duty and Discommendation
When Worf accepts discommendation in TNG "Sins of the Father" to protect the Empire from civil war over Mogh's true innocence, the High Council turns their backs on him. He says nothing aloud. The silence is the most Klingon moment in the entire series.
Later, when his honor is restored in TNG "Redemption," he reclaims it with:
tlhIngan jIH. SuvwI' jIH. mogh puqloD jIH.
"I am a Klingon. I am a warrior. I am the son of Mogh."
On Federation Life
Qov DaH ngugh.
"It is the appropriate moment now." (loose)
Worf to Picard, after winning his vote of confidence as Strategic Operations Officer in DS9. A formal, somewhat stiff line — Worf rarely sounds at ease in conversational Klingon despite his fluency, mirroring his slightly stiff English.
qaStaHvIS wej puq, jIH'e' jIyajchu'.
"Of the three children, I understand myself best."
A Worf-style introspection: the most Klingon-sounding admission of vulnerability he can muster.
On Defeating Duras
After K'Ehleyr's murder, Worf invokes the right of vengeance — bortaS bIr jablu'DI', reH QaQqu' nay': "Revenge is a dish best served cold." (This is the Klingon proverb made famous by Khan in Wrath of Khan, and Worf cites it explicitly.)
He duels Duras and kills him. The line he says before the killing blow:
Hegh batlh DI'on.
"Honored death awaits."
Frequently Asked Questions
Did Michael Dorn speak real Klingon? He delivered lines in Marc Okrand's canonical Klingon, often coached by Okrand directly.
What is Worf's House? Originally House of Mogh. After Mogh's posthumous dishonor, Worf was without a House. He was later adopted into the House of Martok.
Is "Heghlu'meH QaQ jajvam" Worf's invention? No. It is older than Worf in-universe, attributed to Kahless or earlier proverbs.
Why does Worf scream when K'Ehleyr dies? The death scream warns Sto-vo-kor that a Klingon warrior is coming.
What does "Qapla'" mean exactly? Success. Used as a farewell, a battle cry, and an affirmation. See our Qapla' deep dive.

FREQUENTLY ASKED QUESTIONS
What is Worf's most famous Klingon quote?
'Today is a good day to die' — in Klingon, 'Heghlu'meH QaQ jajvam'. It is the line he most often invokes before combat, though it predates Worf in Klingon culture and is widely attributed to Kahless.
Does Worf speak fluent Klingon?
Within the show, yes. Worf was raised by humans on Earth and Gault but studied Klingon language and culture exhaustively. Michael Dorn, the actor, learned to deliver lines in Klingon — Marc Okrand often coached the cast.
What is the meaning of 'Heghlu'meH QaQ jajvam'?
Literally: 'this day is good for one to die.' The suffix -lu'meH marks an indefinite-subject purpose clause. It is less a celebration of death than a statement that the warrior is fully prepared for whatever the day brings.
What did Worf say to K'Ehleyr when she died?
Worf performed the Klingon death scream over K'Ehleyr's body in TNG 'Reunion' — he tilts his head back and roars to warn the afterlife that a Klingon warrior is coming. He then took blood vengeance against Duras.
Did Worf swear the Klingon mating oath?
Worf and Jadzia Dax married in DS9 'You Are Cordially Invited'. Their wedding followed traditional Klingon ritual including the recitation of the legend of Kahless and Lukara.
