Tech-head, intoxicated and showing a bit of leg (5)
I believe the answer is:
thigh
'a bit of leg' is the definition.
('thigh' is part of 'leg')
'tech-head intoxicated' is the wordplay.
'tech-head' becomes 't' (head letter of 'tech-').
'intoxicated' becomes 'high' (similar in meaning).
't'+'high'='THIGH'
'and showing' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for thigh that I've seen before include "top of pin" , "Leg between knee and hip" , "Femoral leg part" , "Upper part of the leg" , "Upper joint of the leg" .)
