Some dread a man temping for firm (7)
I believe the answer is:
adamant
'firm' is the definition.
(thesaurus)
'some dread a man temping' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ADAMANT' is hidden in the letters of 'dread a man temping'.
'for' acts as a link.
(Other definitions for adamant that I've seen before include "Inflexible: fabulously hard rock" , "Definite and unyielding" , "Data man can be quite unyielding" , "Refusing to change opinion" , "popstar" .)
