Female with more unusual stuff to eat (6)
I believe the answer is:
fodder
'stuff to eat' is the definition.
I can't tell whether this definition defines the answer.
'female with more unusual' is the wordplay.
'female' becomes 'f' (common abbreviation).
'with' means one lot of letters go next to another.
'more unusual' becomes 'odder' ('odd' can be similar in meaning to 'unusual').
'f'+'odder'='FODDER'
Can you help me to learn more?
(Other definitions for fodder that I've seen before include "Food for livestock" , "Dried food like hay for horses" , "Lucerne etc" , "Animal feed" , "Bulk feed for livestock" .)
