Make unintelligible order to take off (8)
I believe the answer is:
scramble
'make unintelligible' is the definition.
(thesaurus)
'order to take off' is the wordplay.
I cannot quite see how this works, but
'take' could be 'r' (recipe is latin for take - r is abbreviation) and 'r' is found within the answer.
The remaining letters 'scamble' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for scramble that I've seen before include "Make one's way with disorderly haste" , "Disorderly rush" , "Stir eggs vigorously" , "Disordered mixture" , "Cook beaten eggs" .)
