paper vs a paper — uncountable material vs countable (GiU Unit 70)
The two blanks
Section titled “The two blanks”If you want to know the news, you can read a paper. (= a newspaper) ✓ I want to print some documents, but the printer is out of paper. (= the material) ✓
Per-meaning countability
Section titled “Per-meaning countability”| form | meaning | example |
|---|---|---|
| paper (uncount.) | the material/substance | out of paper, a sheet of paper, recycled paper |
| a paper (count.) | a newspaper | read today’s paper |
| a paper (count.) | an academic essay/talk | gave a paper at the conference |
| papers (count. plural) | documents, ID | my papers, show me your papers |
Unit 70’s point: countability is per-meaning, not per-word. Same noun flips with sense.
Material/substance (no a, no -s) → uncountable. A specific item you could count (one newspaper, two essays) → countable.
JP mirror: 紙 (material) vs 新聞 (newspaper) — English overloads one word, Japanese splits it.
