Then surprisingly right, a learner brings delight (7)
I believe the answer is:
enthral
'delight' is the definition.
(enthralling is a kind of delighting)
'then surprisingly right a learner' is the wordplay.
'surprisingly' indicates an anagram.
'right' becomes 'r' (common abbreviation).
'learner' becomes 'l'.
'then' with letters rearranged gives 'enth'.
'enth'+'r'+'a'+'l'='ENTHRAL'
'brings' is the link.
(Other definitions for enthral that I've seen before include "Totally fascinate" , "be captivating?" , "Beguile" , "Fascinate - grip" , "Hold spellbound" .)
