Very arduous to acquire distance (4)
I believe the answer is:
yard
'distance' is the definition.
(I've seen this before)
'very arduous' is the wordplay.
'YARD' is hidden in amongst the letters.
But, I am uncertain how the hidden word is indicated.
'to acquire' acts as a link.
Can you help me to learn more?
(Other definitions for yard that I've seen before include "Measure of length" , "Police" , "Three feet - enclosed area" , "short distance" , "several feet" .)
