If you searched for “how to spell jeopardize”, you are asking about a word that trips up many writers, and the honest answer is refreshingly simple: the standard American spelling is J-E-O-P-A-R-D-I-Z-E, jeopardize. The confusion usually comes from its relatives: jeopardizing, the -ing form, and jeopardy, the noun it comes from, plus the British spelling jeopardise, which swaps the z for an s. This guide answers how to spell jeopardize clearly, explains the -ing form and its relatives, and shows you how to use the word correctly, so you never have to second-guess it again.
Note the search artifact at the heart of this topic. The file name behind this article mentions “jeopardizing”, and that is part of the confusion: people searching for the base verb often type the -ing form they saw in a sentence, or vice versa. Both forms are correct English; they are simply different forms of the same verb, and this guide covers both, starting with the base spelling itself.
How to Spell Jeopardize: The Correct Spelling
Jeopardize is spelled J, E, O, P, A, R, D, I, Z, E. It has ten letters and four syllables, pronounced roughly JEP-er-dyz. The tricky part is the middle: after “jeop” comes “ard”, not “erd” or “ord”, and the ending is “-ize” in American English. A useful memory aid is to think of the noun jeopardy and add -ize: jeopardy minus the y, plus -ize, gives jeopardize. If you can spell jeopardy, you are most of the way there.
Common misspellings include jeoperdize, jeopordize, jeapordize, jeopardise in American contexts, and jeopardize with a doubled letter, such as jeoppardize. None of these is standard in American English. The most frequent error is swapping the a and the e around the r, writing “jeopredize” or similar, so slow down on the “pard” syllable: J-E-O-P-A-R-D. Saying the word in syllables, jep-ar-dize, while writing it helps lock the order in place.
How to Spell Jeopardize in Its -ing Form: Jeopardizing
When you need the present participle or gerund, the spelling is jeopardizing: J-E-O-P-A-R-D-I-Z-I-N-G. Forming it is straightforward, because the base verb ends in a silent e, and the standard rule is to drop the e before adding -ing: jeopardize becomes jeopardizing, just as “organize” becomes “organizing”. Do not keep the e, and do not double any letter. The same drop-the-e rule gives jeopardized for the past tense and jeopardizes for the third-person singular present, as in “she jeopardizes”.
This is where the search artifact matters most. If you typed “jeopardizing” into a search box, you probably saw the -ing form in a sentence such as “smoking jeopardizes your health” or “the delay is jeopardizing the project”. That sentence is grammatically correct, and jeopardizing is the right word there. But if you need the dictionary form, the infinitive, or the base verb after “to” or “will”, use jeopardize: “do not jeopardize your chances”, “this could jeopardize the deal”. Matching the form to the sentence is what makes the spelling look right in context.
Jeopardize or Jeopardise: American and British Spelling
Both jeopardize and jeopardise are correct, but they belong to different spelling traditions. American English uses -ize, so jeopardize is standard in the United States. British English traditionally allows both -ize and -ise for many verbs, and jeopardise with an s is common in British publishing, though jeopardize with a z is also accepted by many British style guides. The key rule is consistency: pick the spelling that matches your audience and your document’s style, and use it throughout rather than mixing the two.
The same pattern applies to the whole family: American jeopardizing, jeopardized, and jeopardization correspond to British jeopardising, jeopardised, and jeopardisation. Canadian English generally follows the American -ize for this word, while Australian English tends toward -ise. If you are writing for an international audience, the American -ize form is the most widely recognised, which is one reason dictionaries list jeopardize first.
Meaning and Usage: What Jeopardize Actually Means
Jeopardize means to put something at risk, to endanger it, or to threaten its success or safety. It comes from the noun jeopardy, meaning danger or risk, which itself traces back through Old French to a phrase meaning a game of chance, reflecting the idea of risking something on an uncertain outcome. Today the word is used for anything from health and safety to careers, relationships, and negotiations: “missing the deadline could jeopardize the contract” means the deadline failure puts the contract at risk.
Grammatically, jeopardize is a transitive verb, meaning it takes a direct object: you jeopardize something. You would not normally say “he jeopardized” without saying what was put at risk, except in contexts where the object is obvious. It is slightly formal in tone, which is why it appears often in news, legal, and business writing, while everyday speech more often uses “risk” or “put at risk”. Choosing jeopardize signals a serious, consequential risk rather than a trivial one.
How to Spell Jeopardize: The Whole Word Family
| Form | American spelling | British spelling | Example use |
|---|---|---|---|
| Base verb | jeopardize | jeopardise | Do not jeopardize your health. |
| -ing form | jeopardizing | jeopardising | Delays are jeopardizing the launch. |
| Past tense | jeopardized | jeopardised | The error jeopardized the deal. |
| Third-person singular | jeopardizes | jeopardises | She never jeopardizes safety. |
| Noun | jeopardy | jeopardy | His career was in jeopardy. |
| Related noun | jeopardization | jeopardisation | The jeopardization of the project worried investors. |
Memory Tricks for How to Spell Jeopardize
The best trick is the jeopardy connection: jeopardy plus -ize equals jeopardize. If you remember that the noun ends in -pardy, you will remember the verb’s -pard- middle. Another trick is to break the word into chunks: jeo-pard-ize, and to notice that “pard” is a real word element, an old word for a leopard, which is a fun hook even though the etymology runs through the game-of-chance phrase rather than the animal. Chunking beats memorising ten letters in a row, because each chunk is a unit you already know.
Practice also helps more than re-reading. For anyone still unsure how to spell jeopardize after learning the rules, writing the whole word family out in a table, base form, -ing form, and past tense, is a quick way to fix the pattern. Write the word five times from memory, cover it, and write it again. Use it in a sentence of your own, in both the base and -ing forms: “I will not jeopardize my savings” and “overspending is jeopardizing my savings”. If your spellchecker flags jeopardise in an American document or jeopardize in a strictly British one, that is a style setting, not proof that you spelled the word wrong in any absolute sense.
How to Spell Jeopardize in Real Sentences
Seeing how to spell jeopardize in context helps the spelling stick far better than memorising letters in isolation. Consider these examples, each using a different form. Base form: “The company refused to jeopardize its reputation for a quick profit.” Third-person singular: “A single missed safety check jeopardizes the whole operation.” Past tense: “The late delivery jeopardized the contract, though the client eventually renewed it.” And the -ing form: “Rushing the launch is jeopardizing months of careful work.” In each case, the spelling follows the same stem, J-E-O-P-A-R-D, with only the ending changing.
Notice also how the word’s tone fits serious consequences. Writers reach for jeopardize when the risk matters: health, safety, a career, a negotiation, a hard-won reputation. For minor risks, simpler words such as “risk” or “threaten” usually fit better and sound more natural. Overusing a formal word dulls its impact, so reserve jeopardize for situations where something genuinely valuable is at stake. When you do use it, double-check the middle syllable, “pard”, and remember to drop the silent e before -ing: jeopardizing, never jeopardizeing. With that rule and the jeopardy connection in mind, the question of how to spell jeopardize answers itself every time.
