Girl compelled to speak? (4)
I believe the answer is:
maid
'girl' is the definition.
(maid is a kind of girl)
'compelled to speak?' is the wordplay.
'compelled' becomes 'made'.
'to speak?' shows a homophone (sound like) (I've seen 'speak' mean this).
'made' is a homophone of 'MAID'.
(Other definitions for maid that I've seen before include "Young woman - servant" , "Serving girl" , "- - -of-all-work" , "Damsel" , "Female domestic servant" .)
