Inspire some children thus excited (7)
I believe the answer is:
enthuse
'inspire' is the definition.
(I've seen this before)
'some children thus excited' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'ENTHUSE' is hidden in the letters of 'children thus excited'.
(Other definitions for enthuse that I've seen before include "Make keen" , "Show eager interest and liking" , "Cheer" , "Gush in praise" , "Show lively interest and keenness" .)
