Obtain a portion of sausage toad (3)
I believe the answer is:
get
'obtain' is the definition.
(synonyms)
'a portion of sausage toad' is the wordplay.
'a portion of' says the answer is hidden in the clue.
'GET' is hidden in the letters of 'sausage toad'.
(Other definitions for get that I've seen before include "Procure from vegetables" , "Acquire" , "Fetch or obtain" , "Procure or secure" , "See 18" .)
