Feeling movement after start of earthquake (7)
I believe the answer is:
emotion
'feeling' is the definition.
(I know that emotion is a type of feeling)
'movement after start of earthquake' is the wordplay.
'movement' becomes 'motion' (synonyms).
'after' says to put letters next to each other.
'start of earthquake' becomes 'e' (I can't explain this - if you can you should believe this answer much more).
'motion' put after 'e' is 'EMOTION'.
Can you help me to learn more?
(Other definitions for emotion that I've seen before include "Intense feeling" , "sense" , "Agitation of mind" , "Passion" , "Mental agitation" .)
