The article system in English, with its numerous rules and exceptions, is one of the more difficult areas to master: This unit builds on students' understanding of count and non-count nouns from the preceding unit and teaches article usage (a/an, zero article, the) in relation to nouns that are:
- countable vs. non-countable
- specific vs. non-specific
- definite vs. indefinite
- generic vs. specific
- unique
- geographical names
