Re: skristi/skraidyti, I couldn't tell which to pick. Would you believe that my dictionary doesn't indicate perfective/imperfective/determinate/indeterminte conditions of transitive verbs? A good Lithuanian/English dictionary/phrasebook would be so valuable.

Negaliu girdėti was meant to be an example of making something understood on limited knowledge of the language. But it's certainly helpful to know the right way to say it!

Thanks, as always, for the comments. With the exception of skristi, I think I actually did much better this week! :)

išeiti means to leave
išvažiuoti to leave as well but by a vehicle
fly is skristi, skraidyti is to often fly
klausyti is fine for to listen too

You have to know the present III person form in order to conjugate to other forms and you can't always get this form from the infinitive for a conjugation verbs.

Just for the record, the word for hungry is alkanas.

Negaliu girdėti sounds very awkward. You must always say 'negirdžiu' or more likely 'neišgirdau' from išgirsti išgirsta išgirdo.
