Stomp with energy in older jazz style (5)
I believe the answer is:
tread
'stomp' is the definition.
(I've seen this before)
'energy in older jazz style' is the wordplay.
'energy' becomes 'e' (physics symbol as in E=mcr).
'in' means one lot of letters goes inside another.
'older jazz style' becomes 'trad' (I can't justify this - if you can you should give a lot more credence to this answer).
'e' placed inside 'trad' is 'TREAD'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for tread that I've seen before include "Walk; part of tyre" , "Trample" , "Step (heavily)" , "way of dancing" , "Grooves on tyre" .)
