So that till's working at the start (2,5,2)
I believe the answer is:
in order to
'so' is the definition.
(thesaurus)
'till's working at the start' is the wordplay.
I cannot quite understand how this works, but
'working' could be 'inorder' (I've seen this before) and 'inorder' is found within the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
A single letter 'o' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'that' acts as a link.
Can you help me to learn more?
(Another definition for in order to that I've seen is " So one can".)
