Dorothy's period in Hollywood? (3)
I believe the answer is:
dot
This clue might be a double definition.
'dorothy's' is the first definition.
(nickname for someone called Dorothy)
'period in hollywood?' is the second definition.
'dot' can be an answer for 'period' (as in a full stop). I am unsure of the 'in hollywood?' bit.
Can you help me to learn more?
(Other definitions for dot that I've seen before include "Very small circular shape" , "Speck; dowry" , "Shorter of the two signals used in Morse code" , "One signal used in Morse code" , "Internet punctuation mark" .)
