Zero article means using a noun with no article before it. English often uses zero article for general meaning, for many names, and in some fixed expressions. The meaning can change when you add a or the, so zero article is a real pattern, not only an omission.

Use zero article with plural count nouns when you mean all things of that type in general. The noun does not point to one group that the listener already knows. This use is common in facts, opinions, and broad statements.

Use zero article with uncountable nouns when you speak about a substance, activity, or idea in general. This includes many abstract nouns and materials. If the meaning becomes specific, English often uses the.

Most proper nouns take zero article. This includes personal names, most cities, most countries, most streets, and languages. Some names are fixed with the, and learners need to notice them as part of the name.

Zero article is common with meals, days, months, and many time expressions. These words act like names of repeated parts of life and the calendar. English also has fixed exceptions, especially when the time is made specific.

Some expressions use zero article because the whole phrase is fixed. This is common after certain prepositions and in patterns about place, movement, and routine. These forms are often learned as complete phrases.
