Small gates made by village aliens (7)
I believe the answer is:
wickets
'small gates' is the definition.
'wickets' can be an answer for 'gates' (wicket is a kind of gate). I am not sure about the 'small' bit.
'village aliens' is the wordplay.
'village' becomes 'wick' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'aliens' becomes 'ETs' (ET is short for extraterrestrial).
'wick'+'ets'='WICKETS'
'made by' acts as a link.
Can you help me to learn more?
(Another definition for wickets that I've seen is " Sets of stumps".)
