For each pigheaded hesitation (3)
I believe the answer is:
per
'for each' is the definition.
('per' can mean for each)
'pigheaded hesitation' is the wordplay.
'pigheaded' becomes 'p' (this could be a standard abbreviation of which I'm unaware).
'hesitation' becomes 'er' (sound made while hesitating - um, er).
'p'+'er'='PER'
Can you help me to learn more?
(Other definitions for per that I've seen before include "For each or every" , "According to" , "Preposition indicating by means of" , "Preposition meaning for each" .)
