What are the semantic differences between these three verbs? My feeling is that while baiThnaa is the basic verb, baiTh jaana conveys motion ("to go sit") and baiTh lenaa would be equivalent to the English "to take a seat". Have I understood correctly? It also seems to me that, for example, baiTh jaa'o would be a more direct (maybe even more forceful?) command ("go sit down!") compared to baiTh lo ("take a seat"). Is that right? Finally, I would appreciate recommendations for a good (preferably somewhat comprehensive) source for these types of compound verbs in Hindi/Urdu. Dictionaries typically offer only the simple verb form, so aside from listening to contextual use it's hard to know when to say X karo vs. X kar lo or what have you, and I fear that my over-reliance on simple (non-compund) verbs makes my speech sound stilted.
