Well I now have "an answer for everything" (like the Master of wit and repartee), but some of the last few I have no idea on the parsing, and I can only see 9 .......s at the moment.
My 17 is very tenuous - in fact I have only the definition ( and that isn't exact). I'll say no more, as it might prevent you from getting the correct answer (in contrast to mine, that is!)
