15 English as a Second Language
Though most of the structure of the English language is similar to other languages, there are some peculiar rules to English that need attention:

With very few exceptions, English sentences always require a subject.

Generally, use definite articles (the) before specific nouns, while indefinite articles (a, an) precede non-specific nouns.

And as in many languages, English verb conjugations have a life of their own.

On these and other ESL-related issues, consult the Brief English Handbook for more details.
