Reading University impeding a girl (7)
I believe the answer is:
perusal
'reading' is the definition.
(I know that perusal is a type of reading)
'university impeding a girl' is the wordplay.
'university' becomes 'U' (abbreviation for university).
'impeding' indicates putting letters inside (inserted letters impede or disrupt the word).
'a' becomes 'per' (eg 'one a day' means 'one per day').
'girl' becomes 'Sal' (feminine given name).
'per'+'sal'='persal'
'u' placed into 'persal' is 'PERUSAL'.
(Other definitions for perusal that I've seen before include "Thorough reading" , "Examination, survey" , "Study or scrutiny" , "Careful look" , "Inspection" .)
