Gushing movement in each lake (9)
I believe the answer is:
emotional
'gushing' is the definition.
(synonyms)
'movement in each lake' is the wordplay.
'movement' becomes 'motion' (synonyms).
'in' is an insertion indicator.
'each' becomes 'ea' (abbreviation).
'lake' becomes 'L' (geographical abbreviation).
'motion' inserted within 'ea' is 'emotiona'.
'emotiona'+'l'='EMOTIONAL'
(Other definitions for emotional that I've seen before include "Showing feelings like love or fear" , "tear-jerking" , "Very affected; upset" , "Deeply feeling" , "Dramatic" .)
