Trimming margins, act as soon as yours truly has plan (8)
I believe the answer is:
conceive
'plan' is the definition.
(thesaurus)
'trimming margins act as soon as yours truly' is the wordplay.
I cannot really understand how this works, but
'yours truly' could be 'i' and 'i' is found within the answer.
'as soon as' could be 'once' (once can mean immediately after) and 'once' is found in the answer.
This explanation may well be incorrect...
'has' acts as a link.
Can you help me to learn more?
(Other definitions for conceive that I've seen before include "Become pregnant - imagine" , "Have the idea for" , "Form thought in the mind - or become pregnant" , "Envisage - become pregnant" , "Design" .)
