Irish girl in place of learning lacking good name (7)
I believe the answer is:
colleen
'irish girl' is the definition.
(I've seen this before)
'place of learning lacking good name' is the wordplay.
'place of learning' becomes 'college' (I've seen this before).
'lacking' is a deletion indicator.
'good' becomes 'g' (abbreviation).
'name' becomes 'n' (common abbreviation e.g. on forms).
'college' with 'g' taken out is 'collee'.
'collee'+'n'='COLLEEN'
'in' is the link.
(Other definitions for colleen that I've seen before include "Young Irish woman" , "Irish lass" , "Irish girl, English version" , "Irish miss" , "Gaelic girl with English spelling" .)
