Chapter 1-4-3: When No Article Precedes a Noun
Unlike in French, there are times when a noun is not preceded by an article at all.
One occasion where no article can be found before a noun or noun phrase is when the speaker or writer is generalizing or being non-specific about something. For example:
Pens are becoming obsolete. (Pens, in general, are no longer needed).
Children should be seen and not heard. (In general, we shouldn't be bothered by children).
In the news this week, trees mysteriously disappeared. (We won't be specific and tell you which trees disappeared).
Articles are generally not used when referring to names of sports, academic subjects, people, titles, languages, nationalities (unless referring to a nation’s population), and countries. For example:
Thesoccer is a fun game. TheBiology is an easy course. TheDoctor Penfield has a street named after him. TheChinese is a difficult language to learn. TheCanada won a medal.
