'puff of smoke' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'lump collapsed with energy' is the wordplay.
'collapsed with' indicates an anagram.
'energy' becomes 'e' (physics symbol as in E=mc2).
'lump' with its letters mixed up with 'e' makes 'PLUME'.

'and' is the link.

Can you help me to learn more?

(Other definitions for plume that I've seen before include "Feather; column of smoke" , "Large showy feather" , "Smoke when rising" , "A fancy feather" , "Conspicuous feather of a bird" .)
