Persue or Pursue: Which Spelling Is Correct?

Type the word quickly and persue can feel entirely natural, yet it is wrong every single time. The verb is pursue, spelled p-u-r-s-u-e, whether you are chasing a suspect, a deadline, or a dream. Swapping in per- produces a spelling that no dictionary accepts, which lands pursue vs persue squarely among the commonly confused words that trip writers on a single prefix rather than on meaning. What follows is the history behind the pur-, the reason per- feels so tempting, and a memory hook that keeps the U where it belongs.

The Correct Spelling

Only one spelling is right: pursue. Use it for every sense of the verb, to chase ("the dog pursued the ball"), to seek or work toward ("she plans to pursue medicine"), or to press a matter ("they chose not to pursue charges"). The word keeps its shape across tenses too: pursued, pursuing, pursues, all with the pur- opening intact.

There is no dialect or register that rescues persue. Some confused pairs, such as totaling and totalling, split cleanly between American and British usage, and both are correct in their own territory. Persue is not one of them; it has no home. When in doubt, reach for pursue and you will be right for any reader, anywhere.

Tracing Pursue Back to Latin

The U has a pedigree. Pursue reaches English through Middle English pursuen and Anglo-Norman pursuer, and behind those sits the Latin prosequi, later Vulgar Latin prosequere. That verb is built from two pieces: pro-, meaning forward or onward, and sequi, meaning to follow. To pursue something is, quite literally, to follow it forward.

As the word travelled through Norman French into English, the Latin pro- was reshaped into pur-. That single detail explains the whole spelling: the opening syllable preserves the forward-motion prefix, not the per- that writers so often substitute. Knowing the word means follow forward gives the U a reason to exist, and a reason is far easier to remember than a rule.

The Whole Family Keeps the U

Pursue does not travel alone. It heads a small family whose members all open with pur- and all keep the U:

• pursuit, the chase itself or a chosen activity ("in pursuit of happiness");
• pursuer, the one doing the chasing;
• pursuant, a formal term meaning in line with ("pursuant to the agreement");
• pursuance, the act of carrying something out.

Because every one of these words shares the pur- opening, they reinforce each other. If you can spell pursuit, a word most people write without hesitation, you already know how pursue begins. The U is a family trait, not a quirk of one word.

Why Writers Reach for Per-

If pur- is so well grounded, why does persue appear so often? The pull comes from frequency. English is full of common words that open with per-: perceive, perform, persist, persuade, persevere. That prefix is simply more familiar to the eye and the hand than pur-, so writers generalize it onto pursue without a second thought.

Persuade deserves special blame. It sits close to pursue in both sound and sense, and it genuinely begins with per-, so it quietly nudges pursue toward the same opening. Add the fact that persue and pursue sound almost identical when spoken, and nothing in the ear flags the error. The correction is not a sharper sense of sound but a remembered fact: the prefix is pur-, the one that means forward.

Pursue vs Persue: Side by Side

Setting the two forms against each other makes the verdict plain.

Aspect	Pursue	Persue
Prefix	pur-	per-
Correct?	yes, everywhere	no, always an error
Root	Latin prosequi (follow forward)	none; a misspelling
Family	pursuit, pursuer, pursuant	—
US–UK split?	none; both agree	—

The row that settles it is "correct?": pursue holds in every variety of English, while persue belongs to no dialect at all.

A Memory Hook for the U

Pair pursue with purpose. Both begin with pur-, and in practice you tend to pursue a purpose, so the two words lock together naturally. Say them as a phrase, "pursue a purpose," and the shared opening does the remembering for you.

If a second anchor helps, fall back on pursuit. You almost certainly spell that noun with a U already; pursue simply keeps the same pur- start before finishing with -sue. Picture the U planted firmly between the R and the S, holding the word open. Once that image sticks, per- at the front of the word will read as plainly wrong.

Related Spelling Mixups

Pursue vs persue joins a set of confusions that turn on a single prefix or silent letter rather than on meaning. One close cousin is insue vs ensue, where the correct en- opening gets swapped for a non-existent in-, exactly the kind of prefix mix-up that produces persue. Another is perfer vs prefer, which scrambles the letters of a pr- prefix much as persue mishandles pur-. Each pair rewards the same habit: pin down the prefix, and the spelling stops being a guess.

Conclusion

The contest between pursue and persue is over before it begins. Pursue, spelled with pur-, is the only correct form; persue, with per-, is an error in every dialect and every dictionary. The U traces straight back to Latin prosequi, follow forward, and it runs through the whole family, pursuit, pursuer, pursuant, pursuance. Writers drift toward per- only because that prefix is so common elsewhere and because persuade sits so close by. Tie pursue to purpose, lean on the U you already write in pursuit, and the correct spelling will come without effort.
