Use a or an for one non-specific countable thing. Use the when the reader can identify which thing you mean. Use no article for most general plural and uncountable nouns. Choose a/an by sound, not spelling.
| Use | Example | Why it works |
|---|---|---|
| First mention | I found a useful article. | The reader does not yet know which article. |
| Known item | The article explains commas. | The same article is now identified. |
| General meaning | Articles can change an opinion. | General plural nouns usually need no article. |
Check: An university
Use: A university
Listen to the initial /y/ consonant sound; spelling alone does not decide a or an.
