Worth adjusting launch (5)
I believe the answer is:
throw
'launch' is the definition.
(thesaurus)
'worth adjusting' is the wordplay.
'adjusting' is an anagram indicator.
'worth' is an anagram of 'THROW'.
(Other definitions for throw that I've seen before include "blanket" , "Try not to win" , "Hurl, fling" , "shot-put event?" , "puzzle" .)
