Play part in booking learner (4,4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
king lear
'play' is the definition.
(I've seen this before)
'part in booking learner' is the wordplay.
'part in' indicates a hidden word.
'KING LEAR' is hidden within 'booking learner'.
(Other definitions for king lear that I've seen before include "Shakespeare tragedy" , "Shakespeare's foolish, fond old man" , "Part of ruler" , "drama" , "Shakespearian royal tragedy" .)
