Elevation of some horrid gentlemen (5)
I believe the answer is:
ridge
'elevation' is the definition.
(I know that ridge is a type of elevation)
'some horrid gentlemen' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'RIDGE' is hidden in the letters of 'horrid gentlemen'.
'of' acts as a link.
(Other definitions for ridge that I've seen before include "Long raised band" , "Raised earth between furrows" , "high-pressure area" , "Elongated area of high pressure" , "Feature of mountain" .)
