Trying to rise, shattered crossword setter (8)
I believe the answer is:
tiresome
'trying' is the definition.
(thesaurus)
'to rise shattered crossword setter' is the wordplay.
'shattered' indicates an anagram.
'crossword setter' becomes 'me' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to'+'rise'='torise'
'torise' anagrammed gives 'tireso'.
'tireso'+'me'='TIRESOME'
Can you help me to learn more?
(Other definitions for tiresome that I've seen before include "Annoying, makes you fed up" , "Rather boring" , "Wearying" , "Causing boredom" , "Boring, irksome (colloq.)" .)
