Agrees to admit scholar gypsies (6)
I believe the answer is:
nomads
'gypsies' is the definition.
(I've seen this before)
'agrees to admit scholar' is the wordplay.
'agrees' becomes 'nods' (I've seen this before).
'to admit' means one lot of letters goes inside another.
'scholar' becomes 'ma'.
'nods' placed around 'ma' is 'NOMADS'.
(Other definitions for nomads that I've seen before include "They travel all year round" , "Itinerants" , "Damson for wanderers" , "They travel from place to place with no permanent home" , "Damson consumed by rovers" .)
