Take the wrong way and land in crazy situation (7)
I believe the answer is:
mislead
'take the wrong way' is the definition.
'mislead' can be an answer for 'take' (misleading is a kind of taking). I am not certain of the 'the wrong way' bit.
'land in crazy situation' is the wordplay.
'land' becomes 'isle' (isle is a kind of land).
'in' means one lot of letters goes inside another.
'crazy situation' becomes 'mad' (I can't explain this - if you can you should believe this answer much more).
'isle' put into 'mad' is 'MISLEAD'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for mislead that I've seen before include "Hoodwink" , "Cause someone to have a false belief" , "Take someone in the wrong direction" , "Fool" , "Give a wrong impression to (someone)" .)
