Thin and straggly, see the tragic princess upset, supported by the old queen inside! (7)
I believe the answer is:
spidery
'thin' is the definition.
Although both the answer and definition are adjectives, I cannot understand how one could define the other.
'straggly see the tragic princess upset supported by the old queen inside' is the wordplay.
I cannot really understand how this works, but
'princess' could be 'p' and 'p' is present in the answer.
'by' could be 'side' (synonyms) and 'side' is found within the remaining letters.
'queen' could be 'r' (abbreviation for regina, e.g. in ER ) and 'r' is located in the answer.
A single letter 'y' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for spidery that I've seen before include "(Of writing) thin and straggly" , "(Of writing) thin and straggling" , "Wispy" , "Like a hand" , "Gangly" .)
