Boy going around with buddy admitted burning gel (6)
I believe the answer is:
napalm
'admitted burning gel' is the definition.
The answer and definition can be both substances as well as being singular nouns.
I also know that 'burning' relates to this answer.
'boy going around with buddy' is the wordplay.
'boy' becomes 'man' ().
'going around' is a reversal indicator.
'with' is an insertion indicator.
'buddy' becomes 'pal' (both can mean a friend).
'man' reversed gives 'nam'.
'nam' going around 'pal' is 'NAPALM'.
Can you help me to learn more?
(Other definitions for napalm that I've seen before include "U.S. weapon" , "Incendiary agent" , "Jelly used in fire bombs and flame-throwers" , "Flame thrower ingredient" , "Liquid used in flame-throwers" .)
