The meanings of words used in your books about the British East India Company and its actions in India by and large can be gleaned through your explanations or from the contexts themselves; however, trying to recall the meaning of one, as I browsed later after reading, I went to the computer for clarification, and this is what I found: http://www.lib.mq.edu.au/digital/seringapatam/terminology.html. Maybe if other of your readers would like such a reference, I myself found this to be most useful and enjoyable.
