Cross stars never get sacked (10)
I believe the answer is:
transverse
'cross' is the definition.
(transverse means cross or across)
'stars never get sacked' is the wordplay.
'get sacked' indicates an anagram (letters destroyed or sacked).
'stars'+'never'='starsnever'
'starsnever' is an anagram of 'TRANSVERSE'.
(Other definitions for transverse that I've seen before include "Crosswise" , "Extending across something" , "Situated across something" , "Crossing" , "Extending across (the long axis)" .)
