How it works
Use a/an when introducing one nonspecific countable item, the when the reader can identify the item from earlier mention or shared context, and no article for many general plural or uncountable ideas. Determiners such as this, that, each, and every add reference or distribution. Article choice is not only grammatical; it tells the listener whether an item is new, known, general, or one of several. During revision, track first mention and later reference for important nouns.
Patterns
Introduce then identify
A/an noun… The noun…
Introduce one item, then refer to the now-known item.
General plural
Plural noun without article + plural verb.
Make a broad statement about a category rather than identified members.
Before and after

- Why
- First mention is new; second mention is now identifiable.
- Before

Practice
- Mark first and later noun mentions in one paragraph.
- Choose articles for ten service and community nouns.
- Explain how this proposal differs from a proposal in reference.
Show the answer key
- First singular count nouns usually need a determiner.
- Later identifiable reference commonly uses the.
- This points to a specific nearby idea and should have a clear referent.
