Morphological analysis. Just type the word and press "Посмотреть".

2nd word off the top of my head wasn't found: кащей (он же кащей бессмертный :) So, it looks up the word somewhere, it does not analyze it based on the word itself or similarity to other words.

And I'm not sure if 2nd form for эскадрилья in instrumental (творительный) case is right. Never heard it.

Otherwise might be good for you guys.

try "кощей"

[la-dy-ashley.livejournal.com]

both forms are all right, the 2d one is the old variant.
Ей/Ею is based on the same principle. It's archaic now.

And yeah, good old Кощей...
