Nominally she gets five years (4)
I believe the answer is:
vera
'nominally she' is the definition.
I can't judge whether this defines the answer.
'five years' is the wordplay.
'five' becomes 'V' (Roman numeral).
'years' becomes 'era' (I've seen this in another clue).
'v'+'era'='VERA'
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for vera that I've seen before include "Woman" , "senior songstress?" , "__ Lynn, the forces' sweetheart" , "Girl's name (meaning faith or true)" , "& 16 'The Forces' Sweetheart'" .)
