Speak slowly, attract learner (5)
I believe the answer is:
drawl
'speak slowly' is the definition.
(I've seen this before)
'attract learner' is the wordplay.
'attract' becomes 'draw' ('draw' can be a synonym of 'attract').
'learner' becomes 'l'.
'draw'+'l'='DRAWL'
(Other definitions for drawl that I've seen before include "Slow speech pattern" , "Speak slowly and affectedly" , "Slow, protracted way of speaking" , "Speak with lengthy vowel sounds" , "Speak slowly and protractedly" .)
