Mexican snack from tin turned up at house (5)
I believe the answer is:
nacho
'mexican snack' is the definition.
(I've seen this before)
'tin turned up at house' is the wordplay.
'tin' becomes 'can' (synonyms).
'turned up' shows that the letters should be reversed in order.
'at' says to put letters next to each other.
'house' becomes 'ho' (abbreviation for house).
'can' backwards is 'nac'.
'nac'+'ho'='NACHO'
'from' acts as a link.
(Other definitions for nacho that I've seen before include "Tortilla chip topped with cheese and spices" , "Piece of tortilla served with sauce" , "Nibble" , "Tortilla with cheese, etc" , "Mexican dish" .)
