Dismissed for being filled with enthusiasm? (5)
I believe the answer is:
fired
'dismissed' is the definition.
(synonyms)
'filled with enthusiasm?' is the wordplay.
'filled' becomes 'd' (I can't justify this - if you can you should give a lot more credence to this answer).
'with' says to put letters next to each other.
'enthusiasm?' becomes 'fire' (I've seen this in another clue).
'd' after 'fire' is 'FIRED'.
'for being' acts as a link.
Can you help me to learn more?
(Other definitions for fired that I've seen before include "(Of pottery) baked" , "Dismissed; set off" , "Encouraged" , "sent up in flames" , "Dismissed or ignited" .)
