Quick Answer

Pore is most often a verb in the phrase pore over, meaning to read or study something with great care (pore over a book, pore over the figures); it is also a noun meaning a tiny opening in the skin (clogged pores). Pour is a verb meaning to make a liquid flow (pour the tea, the rain poured down). They are homophones — both pronounced /pɔː/ — so only the spelling tells them apart. Remember: when you mean liquid, choose pour.

Pore and pour are two of the most commonly confused words in English, and it is easy to see why: they sound exactly the same. Words that share the same pronunciation but have different meanings and spellings are called homophones. Because your ear cannot separate them, you have to rely on meaning and a simple spelling trick to choose the right one. The good news is that their meanings are completely different, so once you know which is which, the choice becomes clear.

Using “Pore”

Pore is most familiar as a verb in the phrase pore over, which means to read or examine something very carefully and with great concentration. It is also a noun meaning one of the tiny openings in your skin (or in a leaf or rock) through which liquids and gases can pass. Notice that the verb almost always travels with the word over.

Definition

1. (verb) pore over = to study, read, or look at something closely and with great attention: She pored over the map for hours. 2. (noun) a very small opening in a surface, especially in the skin: Sweat escapes through the pores. The verb sense is the one most often confused with pour.

When to use it

  • Studying or reading something intently: pore over a book, pore over the report
  • Examining details closely: pore over the evidence, pore over the figures
  • Searching carefully through documents: pore over old records
  • As a noun for openings in the skin: open pores, clogged pores
  • In science, for tiny openings in materials: the pores of a leaf, the pores of a rock

pore over the details / figures / evidence.
the pores (noun): Sweat escapes through the pores.

Using “Pour”

Pour is a verb. Its core meaning is to make a liquid flow out of a container in a steady stream. It also describes liquid flowing heavily by itself (as with rain) and, by extension, large numbers of people or things moving in a steady flood. If your sentence involves liquid, rain, or a steady stream, you almost certainly want pour.

Definition

1. To make a liquid or substance flow from a container: He poured the milk into the jug. 2. (of rain) to fall heavily: It poured all afternoon. 3. (figuratively) to move or arrive in large amounts: People poured into the stadium; letters poured in. It appears in phrases such as pour out (express freely) and pour with rain.

When to use it

  • Making a liquid flow from a container: pour the tea, pour a glass of water
  • Describing heavy rain: it poured down, it was pouring with rain
  • Large numbers moving steadily: crowds poured into the hall
  • Expressing feelings freely: she poured out her heart
  • Investing heavily: they poured money into the project

Could you pour me a cup of tea, please?

The rain poured down all afternoon, flooding the streets.

As the gates opened, fans poured into the stadium.

She poured the batter carefully into the cake tin.

The company poured millions into research and development.

Key Patterns

pour + liquid: pour the tea, pour the milk
pour with rain / pour down: it poured all day
pour into / out: crowds poured into the hall

The Key Difference: Study vs Liquid

The single most important thing to remember is that pore and pour have nothing to do with each other in meaning — they just happen to sound the same. Pore (as a verb) is about studying or reading something carefully. Pour is about liquid flowing. If you can replace the word with “study” or “read closely,” you want pore. If you can replace it with “tip out” or “flow,” you want pour.

Study / read closely → pore:

He pored over the ancient manuscript. (= studied it carefully)

Tip out / flow → pour:

He poured water over the manuscript by accident. (= liquid flowed)

Because they are homophones, no listener can hear the difference — the spelling only matters in writing. So when you write, pause and ask yourself: am I talking about studying, or about liquid? That one question solves almost every mistake.

Common Mistakes

Special Expressions and Fixed Phrases

  • clogged / open pores — the tiny openings in the skin: clean your pores

Memory Tip

For pore, think of how your eyes explORE and absORB the text when you read closely — pORE and explORE share the same ending and the same idea of careful study. For pour, think of liquid flowing OUT: the letters OUR are right there in p-OUR, just like an outpour of water. If you can swap the word for “study” or “read closely,” choose pore; if you can swap it for “tip out” or “flow,” choose pour.

Frequently Asked Questions

What is the difference between pore and pour?
Pore and pour sound exactly the same but mean completely different things. Pore is usually a verb in the phrase pore over, meaning to study or read something carefully: she pored over the map for hours. It is also a noun meaning a tiny opening in the skin. Pour is a verb meaning to make a liquid flow: pour the tea; the rain poured down. A simple test: if the word means "study closely," use pore; if it means "make liquid flow," use pour.
Is it "pore over" or "pour over" a book?
When you mean to read or study a book carefully, the correct spelling is pore over: she pored over the textbook all night. The verb pore means to examine something intently, and it almost always appears with over. Writing "pour over a book" is a very common mistake, because pour is about liquid. Unless you are literally tipping water onto the book, you want pore over.
Are pore and pour homophones?
Yes. Pore and pour are homophones, which means they are pronounced exactly the same way — both /pɔː/ in British English — but they are spelled differently and have different meanings. Because they sound identical, you cannot tell them apart by listening; you can only tell them apart in writing by the spelling and by the meaning of the sentence. This is why they are so easy to mix up.
What does "pore over" mean?
To pore over something means to read, study, or examine it with great care and concentration. For example: the lawyers pored over the contract, checking every clause, or he pored over old photographs for hours. It always uses the spelling pore and almost always comes with the word over (you can also pore through documents). It has nothing to do with liquid.
What does "pour" mean?
Pour is a verb meaning to make a liquid flow steadily from a container: he poured the milk into the jug. It also describes rain falling heavily (it poured all day) and, figuratively, large numbers of people or things moving in a flood (crowds poured into the hall; money poured into the project). Whenever the idea involves liquid or a steady stream, the word you want is pour.
What does "pore" mean as a noun?
As a noun, a pore is one of the tiny openings in a surface through which liquids or gases can pass. In everyday English it usually refers to the small openings in your skin: sweat escapes through the pores, and a cleanser can help unclog blocked pores. In science, plants and rocks also have pores. The noun is always spelled pore, never pour.
How do I spell the past tense of these words?
For pore, the past tense and past participle are pored, and the -ing form is poring: she pored over the figures; he is poring over the map. For pour, the past tense and past participle are poured, and the -ing form is pouring: she poured the tea; it was pouring with rain. Notice the e drops before -ing in both: poring and pouring.
How can I remember which spelling to use?
A handy trick is to link pore with the idea of study: when you read closely, your eyes explORE and absORB the text, and pORE shares that ending. Link pour with liquid: the letters OUR sit inside p-OUR, like an outpour of water. So if the sentence is about reading or examining, write pore; if it is about liquid or a steady flow, write pour.
Can "pour" be used for people, not just liquid?
Yes. Although pour literally means to make a liquid flow, it is also used figuratively for large numbers of people or things moving in a steady stream: fans poured into the stadium; complaints poured in after the announcement; the firm poured money into research. The image is still one of a heavy, flowing stream, so the spelling stays pour, not pore.
Is "pour over coffee" ever correct?
Yes, in one specific case. "Pour-over coffee" is a brewing method where you pour hot water over ground coffee, so here pour is correct because real liquid is involved. But if you mean studying something carefully, such as reading a book or report, the correct phrase is pore over, with pore. Always ask whether liquid is actually being poured: if not, use pore.
