I think I've finally got all 7 words generated by the extra words/clues and also the 2 letter abbreviations, my problem is assigning each two letter abbreviation to a specific word - the seventh word seems obvious because it's named after him but I can't see any pattern for assigning the others, no doubt I'm missing something obvious but what?
In that one you'll see what the preamble means by 'nominally derived', brendan - the rest work in the same way - the 2nd thematic clue answer is a good place to start.
Not too good, I dropped it at the end of year three, though I have put my seven extra words in to Google Translate but with no good results. 'Kr' for example, I cannot marry that with any of my extra words? Same with the others, bar Mr Ogan......
