Is out of place in ethical considerations! (6)
I believe the answer is:
ideals
'ethical considerations' is the definition.
The definition and answer can be both related to thinking as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'is out of place' is the wordplay.
'out' means to remove the last letter.
'of place' becomes 'deals' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'is' with its last letter taken off is 'i'.
'i'+'deals'='IDEALS'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for ideals that I've seen before include "Standards for attainment or imitation" , "Models of excellence" , "Standards of perfection" , "Dreams" , "Models; principles" .)
