"We do not know Martha."

Translation: Nie znamy Marty.

[Miknairb]

I'm quite amazed how many different forms of 'Martha' there are !!

[immery]

do you mean declension/ cases? or did you include or the diminutives ?

like most feminine nouns there are
Marta/Marty/Marcie/Martę/Martą/Marcie/Marto/
Marty/Mart/Martom/Marty/Martami/Martach/Marty , which makes 10 forms.

but if you add Martunia, Marteczka, Martusia there would be 30 more :)

[Guavalover]

Thank you for your comprehensive answer. I hope my brain can memorize which word goes with which case, etc. Maybe some day !!

[immery]

don't overdo it. It will all come with time. Feminine nouns are not that scary.

How would you know the declensions of a name? What would the declensions of my name be? Or is it only for Polish names?

[Jellei]

Let's say that it's for most names, even foreign ones, but some of them do not undergo declension. And the vast majority of those that don't, are female. I suppose yours would stay the same in every case.

[Jellei]

Okay, checked the rules:

If a feminine name ends in -a (I think every single Polish one does), it undergoes declension. Other female names don't.

If a masculine name ends with a consonant in pronunciation, it undergoes declension. As well as those that end with -a, -o (apart from the short ones like Leo), -y, -i. Not the ones with -u sound at the end (Andrew, Hugh). But most of them undergo declension.

I'm Gabriel, would my name change? I pronounce the l like the english w , so the way I say it it wouldn't change, but you might pronounce it differently.

[Jellei]

Yes, it would undergo declension like most of the names.

Nom: Gabriel, Gen: Gabriela, Dat: Gabrielowi, Acc: Gabriela, Instr: Gabrielem, Loc: Gabrielu, Voc: Gabrielu!/Gabriel!

I actually have a half-Brazilian, half-Polish friend at work, his name is also Gabriel :)
