Fierce type good in row (5)
I believe the answer is:
tiger
'fierce type' is the definition.
The answer and definition can be both people as well as being singular nouns.
I also know that 'fierce' relates to this answer.
'good in row' is the wordplay.
'good' becomes 'g' (abbreviation).
'in' indicates putting letters inside.
'row' becomes 'tier' (a tier is a row of things).
'g' inserted within 'tier' is 'TIGER'.
Can you help me to learn more?
(Other definitions for tiger that I've seen before include "Shere Khan's type" , "Striped feline" , "Large striped cat" , "Striped animal poetically burning bright" , "''... ... burning bright, in the forests of the night'' (Blake)" .)
