Wail of female singer rising at start of event (7)
I believe the answer is:
ululate
'wail' is the definition.
(I know that wail can be written as ululate)
'female singer rising at start of event' is the wordplay.
'female singer' becomes 'lulu' (I've seen this before. I am not sure about the 'female' bit.).
'rising' says the letters should be written backwards (going up in a down clue).
'start of' indicates taking the first letters.
The first letter of 'event' is 'e'.
'lulu' written backwards gives 'ulul'.
'ulul'+'at'+'e'='ULULATE'
'of' is the link.
Can you help me to learn more?
(Other definitions for ululate that I've seen before include "Howl, wail, screech" , "Emit long, loud wails" , "Keen" , "Give a hoot" , "Wail or lament loudly" .)
