Temperature at elevated part of the leg (5)
I believe the answer is:
thigh
'part of the leg' is the definition.
('thigh' is part of 'leg')
'temperature at elevated' is the wordplay.
'temperature' becomes 't' (abbreviation).
'at' means one lot of letters go next to another.
'elevated' becomes 'high' (I've seen this in another clue).
't'+'high'='THIGH'
(Other definitions for thigh that I've seen before include "Joint of meat" , "Leg between knee and hip" , "Femoral leg part" , "Upper part of the leg" , "Ham" .)
