Fine stranger has straw to eat? (6)
I believe the answer is:
fodder
'straw to eat?' is the definition.
(I've seen this before)
'fine stranger' is the wordplay.
'fine' becomes 'f' (abbreviation in pencil classifications).
'stranger' becomes 'odder' (more odd).
'f'+'odder'='FODDER'
'has' acts as a link.
(Other definitions for fodder that I've seen before include "Straw to eat" , "Bulk feed for livestock" , "Animal feed" , "Lucerne etc" , "Food for animals" .)
