Vague specialist following exercise in low-pitched gable (8)
I believe the answer is:
pediment
'low-pitched gable' is the definition.
'pediment' can be an answer for 'gable' (pediment is a kind of gable). I am not sure about the 'low-pitched' bit.
'vague specialist following exercise' is the wordplay.
'vague' becomes 'dim' (I've seen this before).
'specialist' becomes 'ent' (Ear, Nose and Throat specialist).
'following' is a charade indicator (letters next to each other).
'exercise' becomes 'pe' (Physical Education).
'dim'+'ent'='diment'
'diment' put after 'pe' is 'PEDIMENT'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for pediment that I've seen before include "Triangular space over porch etc" , "It surmounts a portico" , "Structure atop a portico" , "Classical triangular gable" , "Triangular architectural feature" .)
