Everyone put up with mother's animal (5)
I believe the answer is:
llama
'animal' is the definition.
(I've seen this before)
'everyone put up with mother's' is the wordplay.
'everyone' becomes 'all' (I've seen this before).
'put up' says the letters should be written backwards.
'with' means one lot of letters go next to another.
'mother' becomes 'ma' (ma is a kind of mother).
'all' in reverse letter order is 'lla'.
'lla'+'ma'='LLAMA'
(Other definitions for llama that I've seen before include "Andean pack animal" , "wool supplier" , "Andean camelid" , "Andean beast of burden" , "Fleecy mammal" .)
