Except for a thousand, fortune I had is all there (5)
I believe the answer is:
lucid
'all there' is the definition.
(thesaurus)
'except for a thousand fortune i had' is the wordplay.
I cannot really see how this works, but
'i' is within the answer.
'had' could be 'd' (in contractions e.g. 'I'd', 'you'd' etc) and 'd' is present in the answer.
The remaining letters 'luc' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'is' is the link.
Can you help me to learn more?
(Other definitions for lucid that I've seen before include "Clear; making sense" , "Transparently clear" , "Rational, clear" , "Clear; bright" , "Shining, clearly" .)
