Intended new model will break virtually all rules (12)
I believe the answer is:
contemplated
'intended' is the definition.
(thesaurus)
'new model will break virtually all rules' is the wordplay.
I cannot quite see how this works, but
'new' could be 'late' ('late' can be similar in meaning to 'new') and 'late' is found in the answer.
'model' could be 't' (Ford Model T car) and 't' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for contemplated that I've seen before include "Brooded over" , "Thought about" , "Did deliberate" .)
