When using a noun you may wish to refer to it as a generic 'thing' or a specific 'thing'. For example you may talk about 'the table' or 'a table' (any table). In German the first type is stated with der, die, das - the definite articles, and the second type is identified by indefinite articles.
Der Tisch (the table)
Ein Tisch (a table)
Indefinite articles take the form ein ('a' in English) with the ending determined by the gender of the noun it is referring to.
Masculine nouns = ein (ein Tisch)
Feminine nouns = eine (eine Lampe)
Neutral nouns = ein (ein Boot)
There is no indefinite article for plurals since that would make no sense - it would be like saying 'a tables' in English.
