Determiner

A determiner is a class of words that typically functions as a determiner (function) in noun phrases. As such, they establish the reference of a noun or noun phrase, including quantity, rather than its attributes as expressed by adjectives. Despite this tendency, determiners have a variety of functions including, in English, modifiers in adjective phrases and determiner phrases, and even markers of coordination.
This word class, or part of speech, exists in many languages, including English, though most English dictionaries still classify determiners under other parts of speech. Determiners usually include articles, and may include items like demonstratives, possessive determiners, quantifiers, and cardinal numbers, depending on the language.

Articles

First the good news:There are only three articles in English: a, an and the.
There are two types of articles indefinite 'a' and 'an' or definite 'the'. You also need to know when not to use an article.
The bad news is that their proper use is complex, especially when you get into the advanced use of English. Quite often you have to work it out by what sounds right, which can be frustrating for a learner.
