She's a succeeding hammer thrower (5)
I believe the answer is:
thora
'she's' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'a succeeding hammer thrower' is the wordplay.
'succeeding' says to put letters next to each other (succeeding can mean going after or following).
'hammer thrower' becomes 'Thor' (the Norse god Thor wields a hammer).
'a' after 'thor' is 'THORA'.
Can you help me to learn more?
(Other definitions for thora that I've seen before include "lady" , "Hat or change for a girl" , "Actress, dame, who died in 2003" , "Woman" .)
