Pray is a verb meaning to speak to a deity or higher power, or to make an earnest request. Prey is a noun meaning an animal or person being hunted, and a verb meaning to hunt, target, or exploit.
These words are homophones — identical in sound, completely different in meaning. They share no overlap: one is about asking, the other is about hunting.
Quick substitution test: If you can replace the word with hunt, target, or victim, use prey. If you can replace it with ask, hope, or petition, use pray.
What “Pray” Means
Pray is always a verb. It has two main uses.
Speaking to a deity or higher power:
She prayed before the exam.
They prayed for guidance during the crisis.
He knelt down to pray at the small chapel on the corner.
Making an earnest request or expressing a fervent hope:
I pray this works out.
She prayed for good weather on her wedding day.
We prayed the flight would be on time.
Pray never functions as a noun. The noun form is prayer — “a prayer for peace,” “her prayers were answered.”
“Pray” as an Archaic Imperative
In older English — and still in historical fiction, period films, and formal literary writing — pray functions as a polite imperative meaning “please” or “kindly.”
Pray be seated.
Pray tell me what happened.
Pray continue — I want to hear the rest.
Today, “pray tell” survives in contemporary usage, but almost always with a sardonic or rhetorical edge: “And pray tell, how exactly do you plan to fix this?” It always uses pray, never prey — it is a polished request, however ironic, not a predatory act.
What “Prey” Means
Prey functions as both a noun and a verb.
As a noun — an animal or person that is hunted, targeted, or victimized:
The deer became easy prey for the pack of wolves.
The antelope separated from the herd and became prey.
Elderly people living alone are sometimes prey for scammers.
As a verb — to hunt, pursue, attack, or exploit:
The hawk preys on mice and small rodents.
Scammers prey on trust and loneliness.
The virus preys on weakened immune systems.
Where These Words Came From
Their origins are entirely separate — the identical pronunciation is a coincidence of language evolution, not shared ancestry.
Pray traces to Latin precari, meaning “to beg, to ask earnestly” — through Old French preier into Middle English. The same root gives English precarious (originally meaning “obtained by prayer, dependent on the will of another”).
Prey traces to Latin praeda, meaning “booty, plunder, that which is seized.” Praeda also gave Latin praedator (“one who plunders”), which became English predator. The etymology chain — praeda → praedator → predator → prey — makes the hunting family connection explicit and memorable. When you see a predator and its prey, you’re looking at two descendants of the same Latin root.
Idiomatic Uses of “Prey”
“Fall Prey To”
To fall prey to something means to become its victim.
She fell prey to the misleading advertisement.
The city fell prey to decades of neglect.
He fell prey to his own ambition.
“Prey on One’s Mind”
When something preys on your mind, it causes persistent anxiety or distress — it hunts your thoughts and won’t leave.
The decision has been preying on his mind for weeks.
The unsolved question preyed on her mind long after the conversation ended.
This is distinct from “weigh on one’s mind” (which suggests heaviness or burden) — prey on specifically implies something active and intrusive, gnawing at focus and peace.
“Let Us Prey”
A documented centuries-old pun on “let us pray” — used on satirical church signs, political cartoons, headlines about corporate greed, and comedy. It signals predatory behavior under a veneer of piety. This is always deliberate wordplay, not a spelling error. Recognizing it correctly requires knowing both words.
“Praying Mantis” — Always “Praying,” Never “Preying”
This is one of the most common spelling errors involving this pair.
The insect is named for its distinctive posture: its front legs fold upward in a position that resembles hands clasped in prayer. The correct spelling is always praying mantis — the word praying refers to the posture, not the predatory behavior.
The scientific name is Mantis religiosa — the species name means “religious,” directly reflecting the prayer association. Despite the fact that mantises are skilled and voracious hunters, the name comes from appearance, not behavior. Preying mantis, while logical in spirit, is always incorrect.
Common Mistakes and Quick Fixes
Mistake: I preyed for rain all week.
Fix: I prayed for rain all week. — an earnest request; use pray.
Mistake: The hawk prays on mice.
Fix: The hawk preys on mice. — hunting behavior; use prey.
Mistake: I prey you’ll forgive me.
Fix: I pray you’ll forgive me. — earnest appeal; use pray.
Mistake: He has a preying mantis in a terrarium.
Fix: He has a praying mantis in a terrarium. — named for posture, not predation.
Mistake: The scheme preyed on his mind.
Clarification: This is actually correct — “preyed on his mind” means it caused persistent anxiety, and prey (the hunting/attacking sense) is the right word here.

FAQs
What is the difference between pray and prey?
Pray is a verb meaning to speak to a deity or make an earnest request. Prey is a noun meaning an animal or person being hunted, and a verb meaning to hunt, target, or exploit. The words are homophones — identical in pronunciation — but share no meaning and no etymological origin.
Is it “fall pray to” or “fall prey to”?
Fall prey to — always. The expression means to become the victim of something, using prey in its hunting/victimization sense. “Fall pray to” would mean to kneel down and petition something, which is not the intended meaning.
Is it “praying mantis” or “preying mantis”?
Always praying mantis. The insect is named for the prayer-like posture of its folded front legs, not its predatory behavior. The scientific name Mantis religiosa (meaning “religious mantis”) confirms the prayer association. Preying mantis is always incorrect.
What does “prey on one’s mind” mean?
When something preys on your mind, it causes persistent, intrusive anxiety or distress — it actively attacks your peace of thought and keeps returning. It is distinct from “weigh on one’s mind,” which suggests heaviness or passive burden.
What does “pray tell” mean, and is it “pray” or “prey”?
“Pray tell” is an archaic English construction where pray means “please” or “kindly” — a polite imperative. In modern usage it is almost always sardonic: “And pray tell, what is your plan?” It always uses pray (a request), never prey (a hunt).
Where do “pray” and “prey” come from?
They come from entirely separate Latin roots. Pray traces to Latin precari (“to beg, to entreat”) — the same root that gives English precarious. Prey traces to Latin praeda (“booty, plunder”) — the same root that gave Latin praedator and English predator. The identical modern pronunciation is a coincidence of language evolution, not shared ancestry.
The Bottom Line
Pray means to ask, petition, or speak to a higher power. Prey means to hunt, exploit, or to be hunted. Their identical pronunciation is coincidental — their Latin roots are entirely separate, with prey belonging to the same family as predator. Remember the substitution test: hunt or target → prey; ask or hope → pray. And when it comes to the mantis: the name is always praying, regardless of how the insect makes its living.
Conclusion
Pray and prey sound identical but point in completely different directions. One is about speaking to something greater than yourself. The other is about hunting, targeting, or being targeted. Once you lock in the difference — asking versus hunting — the confusion disappears for good.
