Woo with love, in short (5)
I believe the answer is:
court
'woo' is the definition.
(I know that woo can be written as court)
'with love in short' is the wordplay.
'with' indicates putting letters inside.
'love in' becomes 'o' (love means zero in tennis. I am not sure about the 'in' bit.).
'short' becomes 'curt' (synonyms).
'o' placed inside 'curt' is 'COURT'.
Can you help me to learn more?
(Other definitions for court that I've seen before include "Woo; tribunal" , "Where trials take place" , "invite > defendant to appear here" , "Work as solicitor" , "Legal or royal assembly" .)
