Pointed remarks from lawyers with briefs lacking content (5)
I believe the answer is:
barbs
'pointed remarks' is the definition.
(barb can mean a hurtful comment)
'lawyers with briefs lacking content' is the wordplay.
'lawyers' becomes 'bar' (the bar can mean the legal profession).
'with' says to put letters next to each other.
'lacking content' means to remove the middle letters (the content of the word is emptied out).
'briefs' with its middle removed is 'bs'.
'bar'+'bs'='BARBS'
'from' acts as a link.
(Other definitions for barbs that I've seen before include "Hurtful remarks" , "Sedatives" , "Thorns or pointed remarks" .)
