Partitive Plural

[Ian Lemke]

What's the difference between this and just plain old plural? I know the partitive but whats the difference between sanoja and sanat?
And also, what vowel changes do you do to the words?

[Sinikka]

sanat is like.. Nämä sanat ovat erikoisia. (plural)
and sanoja is like En muista kaikkia sanoja. (partitive plural)
you use the partitive plural when its like.. a PART of something.. im bad at explaining..

[yaxxi]

a very simple rule which might help you (although it is not universal, does not always work): the normal plural is often in the beginning of sentences, the partitive plural in the end, meaning an object, especially when you talk about some unspecific amount.

But don't worry, this object thing is difficult for foreigners who have lived dozens of years here.

[AndrewS]

Minä luen kirjoja. I'm reading (some) books.
Minä luen kirjat. I'm reading(shall read) the books.

Kirjat is the accusative plural and here is specific (in mind) about which books, hence "the". Kirjoja, some books, isn't specific about which books, just "some".
