Some brief title for a newt (3)
I believe the answer is:
eft
'a newt' is the definition.
(eft is a kind of newt)
'some brief title for' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'EFT' can be found hidden inside 'brief title for'.
(Other definitions for eft that I've seen before include "Young newt" , "Small amphibian" , "Pond creature" , "Little creature" , "Swimmer with feeble legs" .)
