Write article using this package in the open air beforehand to describe creative thinking (7,3,3)
I believe the answer is:
outside the box
'write article using' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'package in the open air beforehand to describe creative thinking' is the wordplay.
'package' becomes 'box' (synonyms).
'in the open air' becomes 'outside' (I've seen this in another clue).
'beforehand' means one lot of letters go next to another.
'to describe' is an insertion indicator.
'creative thinking' becomes 'the' (I can't justify this - if you can you should give a lot more credence to this answer).
'box' put after 'outside' is 'outsidebox'.
'outsidebox' placed around 'the' is 'OUTSIDE THE BOX'.
'this' is the link.
Can you help me to learn more?
