Geologist ran site screening course (7)
I believe the answer is:
transit
'course' is the definition.
(thesaurus)
'geologist ran site screening' is the wordplay.
'TRANSIT' is hidden in amongst the letters.
But, I am uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for transit that I've seen before include "Conveyance of goods or people - tin star (anag)" , "Moving" , "Haulage" , "Travel" , "The act of carrying from one place to another" .)
