Dad with university material for common people (8)
I believe the answer is:
populace
'common people' is the definition.
(I've seen this before)
'dad with university material' is the wordplay.
'dad' becomes 'pop' ('pop' can be a synonym of 'dad').
'with' means one lot of letters go next to another.
'university' becomes 'u'.
'material' becomes 'lace' (lace is a kind of material**).
'pop'+'u'+'lace'='POPULACE'
'for' acts as a link.
(Other definitions for populace that I've seen before include "Residents" , "General public" , "Inhabitants" , "Masses" , "The plebs" .)
