200-word vocabulary

For the automaton thing I've said that the default vocabulary is 200 words - it seems about right. What I think I now need to do is decide what the most useful 100 or so words are, assuming that the remainder are specialised skill-related words etc. To make things easier I'll assume that plurals etc. of words don't count, e.g. gun, guns are one word (and would be skill-related anyway)

So... suggestions for the core vocabulary?
