Nominative, genitive, partitive: singular
These three cases are called grammatical cases, because they have special role in sentences: they identify the subject and the object. There is also the accusative case, but some grammars don't mention it because it looks like the genitive.
More how to use these cases on the sentence article.
Nominative singular
Nominative is the basic case found in dictionaries, it answers the question what?. Nominative doesn't have any ending in singular.
Genitive singular
Genitive shows the owner, and answers the question whose?. Genitive case ends with n.
- talon
- pihan
- pullon
- verhon
- seinän
- juoman
- kynttilän
- korkean
Consonant gradation makes this little bit more complicated; genitive is usually in the weak grade.

---|---|---|
pappi | papin | (a priest) |
kuppi | kupin | (a cup) |
tukka | tukan | (a hair) |
Pekka | Pekan | |
satu | sadun | (a tale) |
tunti | tunnin | (an hour) |
One exception is words ending with s. Then it's reversed: nominative is in weak grade, and genitive in the strong grade:

hammas | hampaan | (a tooth) |
Note also, that in this word type the last s disappears and the last vowel is long.
Other exceptions and changes on stems:
There are some othee exceptions, as well. Usually the problem is with consonants because you cannot add n after another consontant. That's why the stem transforms.
Words ending nen. Because words cannot end with two n's, that's why nen in the end of the word becomes sen
