Charged first bearing weapon at bosses (11)
I believe the answer is:
spearheaded
'charged first' is the definition.
The answer and definition can be both to do with social activities as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'weapon at bosses' is the wordplay.
'weapon' becomes 'spear' (spear is a kind of weapon).
'at bosses' becomes 'headed' (I can't explain this - if you can you should believe this answer much more).
'spear'+'headed'='SPEARHEADED'
'bearing' acts as a link.
Can you help me to learn more?
(Other definitions for spearheaded that I've seen before include "Pioneered" , "Led" .)
