Expand Women's Institute's meeting-place (5)
I believe the answer is:
widen
'expand' is the definition.
(thesaurus)
'women's institute's meeting-place' is the wordplay.
'women's institute' becomes 'wi'.
'meeting' says to put letters next to each other.
'place' becomes 'den' (den is a kind of place).
'wi'+'den'='WIDEN'
(Other definitions for widen that I've seen before include "Broaden - enlarge" , "Stretch sideways" , "Increase dimension" , "Spread" , "Expand" .)
