“pore” vs. “pour”
Use "pore" (always with "over") for studying something intently, or as the skin-related noun; use "pour" for liquids flowing or figuratively streaming in.
pore
"Pore" wears two hats: as a noun it names a tiny opening in skin or another surface ("clogged pores"), and as a verb, always trailed by "over," it means to study or read something with close, sustained attention ("pore over the documents"). Greek "poros" (a passage or opening) is behind the noun; the verb's history is murkier, possibly tied to an old word for staring fixedly, and the two senses of "pore" were likely never related to each other at all, despite sharing a single modern spelling.
pour
"Pour" describes a liquid or similar substance streaming out of a container ("pour the coffee"), and by extension, something arriving in a steady, heavy rush ("complaints poured in"). Middle English "pouren" is as far back as its trail can be reliably traced, with a tentative, unconfirmed link to Old French "purer" (to purify or strain) suggested by some etymologists.
The real distinction
"Pore" and "pour" are homophones, and the most common real-world error is the fixed phrase "pore over" (to study intently) being mistakenly written as "pour over," an error common enough that it appears regularly even in published writing and news copy. The distinction is genuinely worth memorizing as a fixed idiom: you "pore over" a book, a report, or a set of documents, using the verb related to intense, close visual study, never the liquid-related "pour." "Pour," meanwhile, is correct for literal liquids (pour the wine) and for the figurative sense of something arriving in a steady stream (support poured in after the announcement). The confusion is compounded by "pour-over," a genuinely correct compound noun in coffee culture referring to a manual brewing method where water is poured directly over grounds ("a pour-over coffee maker") — a real, correctly spelled term that looks confusingly similar to the commonly misspelled "pour over" (documents), making context essential: coffee brewing legitimately uses "pour," while studying documents intently always needs "pore." A secondary, much rarer confusion involves the skin-related noun "pore" (as in enlarged pores), which shares no functional overlap with either the studying verb or with "pour" at all, beyond the historical coincidence of identical spelling for two unrelated senses of "pore" itself. Editors reviewing academic, legal, or research writing specifically watch for "pour over" where "pore over" is intended, since the error is common enough to have become one of the more frequently corrected phrases in professional copyediting, right alongside more famous pairs like affect/effect. "Pore" as a verb rarely stands alone, locked into the fixed pattern "pore over [something written or visual]," while "pour" as a verb needs a named liquid or a figurative flow of something arriving nearby, checking what immediately follows the word — a document versus a substance — is frequently a faster real-time test than trying to recall each word's separate etymology while writing quickly.

Memory trick
Remember the fixed idiom "pore over a book": both "pore" and "over" pair together specifically for studying, and the word "pore" itself contains the same letters as "peer," a hint about the close, careful looking involved. "Pour" always involves an actual or figurative liquid flowing, so if you can picture something splashing or streaming, you need "pour" — but studying, reading, or examining closely always calls for "pore," never the liquid-related spelling.
