Building upon the first podcast, this episode covers adding a か ka at the end to change a statement into a question.

何か食べたいです。　I want something to eat.
nanika tabetai desu.

[Note: the 'I' is assumed, but it just as easily be 'you' in the right context.]

To make that into a question, just add か

何か食べたいですか？ Would you like something to eat?
nanika tabetai desu ka

[Notice I didn't say 'Would I like something to eat?' since it is obvious 'you' would be more appropriate]

–
何か飲みたいです。 I want something to drink.
nanika nomitai desu.

何か飲みたいですか？ Would you like something to drink
nanika nomitai desu ka?
