oko / oczy?

The plural of oko is oczy, but is the plural oka still used? Also how about these genitive plural forms: oczu, oczów, ócz and ók? Also instrumental plural forms oczami, oczyma and okami. Are all of these still in use?

For the organ of sight, the plural is always oczy. Oka is used for the liquid fat on the surface of a soup (oka na rosole):


oczu is commonly used. oczów, ócz - these are correct but sound archaic, like in 19th c poetry.
ók - no such form. it's ok (nie lubię ok na rosole)


oczami - common use
oczyma - rarer, but correct
okami - for the things on the rosół

Brilliant answer. Thank you

Read about a dual form in polish language. A lot will become clearer.
