Kind of engineer (5)
I believe the answer is:
civil
'kind of engineer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for civil that I've seen before include "Urbane" , "(Of law) non-criminal" , "Courteously polite" , "Polite to the state" , "Nonviolent refusal to obey laws" .)
