Have same query re 'I'.
I reckon 'first' = Ist, then 'not second' = 'IT'
This leaves 'alian' which I thought might be an alternative spelling for 'alien' but it's not in my dictionary.
Maybe the definition here is just 'C' and the 'T' refers to saying 'alien' so 'alian' could be a homophone ~ bit far fetched perhaps but maybe not for this setter - I love his alphabetical puzzles.
