Sally is kind and gives regularly (6)
I believe the answer is:
sortie
'sally' is the definition.
(I know that sally can be written as sortie)
'kind and gives regularly' is the wordplay.
'kind' becomes 'sort' (synonyms).
'and' is a charade indicator (letters next to each other).
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
The alternating letters of 'gives' are 'ie'.
'sort'+'ie'='SORTIE'
'is' acts as a link.
(Other definitions for sortie that I've seen before include "Attack launched from place of siege" , "Operational flight by a bomber or fighter" , "Short foray" , "Single military flight" , "Military raid" .)
