Learner gets comfort, acquiring contract (5)
I believe the answer is:
lease
'contract' is the definition.
(leasing is a kind of contracting)
'learner gets comfort' is the wordplay.
'learner' becomes 'l'.
'gets' says to put letters next to each other.
'comfort' becomes 'ease' (easing is a kind of comforting).
'l'+'ease'='LEASE'
'acquiring' acts as a link.
(Other definitions for lease that I've seen before include "Contract for, say, use of building" , "Property rental agreement" , "Let out, hire" , "Rent -- easel (anag)" , "Contract to rent" .)
