Sentimental English movement has rally regularly (9)
I believe the answer is:
emotional
'sentimental' is the definition.
(similar in meaning)
'english movement has rally regularly' is the wordplay.
'english' becomes 'E' (abbreviation as in OED).
'movement' becomes 'motion' (synonyms).
'has' is a charade indicator (letters next to each other).
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
The alternate letters of 'rally' are 'al'.
'e'+'motion'+'al'='EMOTIONAL'
(Other definitions for emotional that I've seen before include "Poignant" , "Arousing strong feeling" , "showing passion" , "Loving" , "expressing feelings" .)
