Kind of learning (4)
I believe the answer is:
rote
'kind of learning' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rote that I've seen before include "Repetition for learners" , "Mechanical procedure" , "Repetition from memory" , "Learn by ____ (repetition)" , "By . . . . - from memory without thought" .)
