Standards to be aimed at in island trades (6)
I believe the answer is:
ideals
'standards to be aimed at' is the definition.
(I've seen this before)
'island trades' is the wordplay.
'island' becomes 'i'.
'trades' becomes 'deals' ('deal' can be a synonym of 'trade').
'i'+'deals'='IDEALS'
'in' acts as a link.
(Other definitions for ideals that I've seen before include "Standards to aim for" , "Lofty aspirations for ladies" , "Ideas regarded as perfect or standards" , "Noble aspirations for ladies" , "High standards for ladies" .)
