Offering resistance, experienced absorbing resistance (4)
I believe the answer is:
hard
'offering resistance experienced absorbing resistance' is the definition.
I can't tell whether this definition defines the answer.
'experienced absorbing resistance' is the wordplay.
'experienced' becomes 'had' (have can mean to experience or go through).
'absorbing' is an insertion indicator.
'resistance' becomes 'r' (electronics abbreviation).
'had' going around 'r' is 'HARD'.
Can you help me to learn more?
(Other definitions for hard that I've seen before include "Intensely" , "Difficult; rigid" , "Tough - difficult" , "Difficult; severe" , "Unyielding" .)
