... so that he might, like the friar, recall holy books (2,5,2)
I believe the answer is:
in order to
'so' is the definition.
(thesaurus)
'he might like the friar recall holy books' is the wordplay.
I cannot really understand how this works, but
'he' could be 'der' and 'der' is found in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'that' is the link.
Can you help me to learn more?
(Another definition for in order to that I've seen is " So one can".)
