Developed torso or other bits (5)
I believe the answer is:
roots
'other bits' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Perhaps you can see a link between them that I can't see?
'developed torso' is the wordplay.
'developed' indicates anagramming the letters.
'torso' with letters rearranged gives 'ROOTS'.
'or' is the link.
Can you help me to learn more?
(Other definitions for roots that I've seen before include "Supports" , "Sources, rummages" , "authentic music" , "Radicals" , "Nerve endings" .)
