Language / -ski/-ska, -scy/ski, -wicz - Polish surnames help [185]

I would be happy to get that to know as well, but I guess these ending derives from the case of initial noun (that's the feature of slavic languages).

Let me explain that with some Russian last name. For example "Ivanov". The sense of it is "Ivan's son", although -ov doesn't mean "son", that's just an ending that results as an answer on the question "whose".

- Whose's this son? (Chey eto sin?)
- That's the Ivan's son. (Eto Ivanov sin)

And so on... :) I guess Polish language uses the same logic. Anyway... somebody should enlighten me on this issue.
