Superior and I may be taken in by Spanish man (6)
I believe the answer is:
senior
'superior' is the definition.
(I've seen this before)
'be taken in by spanish man' is the wordplay.
'be' becomes 'i' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'taken in by' indicates putting letters inside.
'spanish man' becomes 'senor' (I've seen this before).
'i' going within 'senor' is 'SENIOR'.
'and i may' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for senior that I've seen before include "Denoting older people" , "High-ranking" , "Elder (of two)" , "Older or higher in standing" , "More advanced in years or authority" .)
