MA thesis

I'm writing my MA thesis at the University of Copenhagen at the moment. The topic is Verb Constructions in Sierra de Zongolica Nawatl and the aim is a complete description and analysis. Is this biting off more than I can chew? I guess we'll see about that in a couple of months. The thesis is due at the end of March 2010.
My theoretical approach is functionalist and as such should focus on the connection between the utterance and the intention of the speaking individual. Or in my case the narrating individual I guess, since much of my data are stories from La Sierra de Zongolica.
Currently I have rough drafts for sections on: future, imperfect past and pluperfect. I have also written something up on the existing studies of this particular Nawa dialect.
One of the sources which I am using, although not as much as I would like, is radio recordings. Need I say more than: Time consuming! Oh yes, and students only have six months for an MA thesis of 60-80 pages.
