Will she do time? (3)
I believe the answer is:
dot
'will she' is the definition.
'Dot' can be an answer for 'she'. I'm not sure about the 'will' bit.
'do time?' is the wordplay.
'time?' becomes 't' (abbreviation).
'do'+'t'='DOT'
Can you help me to learn more?
(Other definitions for dot that I've seen before include "Long-ago year?" , "Full stop, point" , "Very small circular shape" , "Spot, speck" , "Morse symbol; spot" .)
