Common misconceptions
❝ If the noun is singular, I should use the. ❞
Use the only when the noun is specific and identifiable. Many singular nouns use a/an or no article pattern in other structures.
❝ The means the noun is special or important. ❞
The does not mean important. It means the listener can identify exactly which person or thing you mean.
