Husband steers clear of upsets and quarrels (6)
I believe the answer is:
arrows
'husband steers' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Maybe you can see a link between them that I don't see?
'clear of upsets and quarrels' is the wordplay.
'clear of upsets' becomes 'ar' (I can't justify this - if you can you should believe this answer much more).
'and' says to put letters next to each other.
'quarrels' becomes 'rows' ('row' can be a synonym of 'quarrel').
'ar'+'rows'='ARROWS'
Can you help me to learn more?
(Other definitions for arrows that I've seen before include "Missiles for the bowman" , "''To suffer the slings and ... of outrageous fortune'' (Hamlet)" , "Darts" , "The archer's missiles" , "red ones displayed at airshows" .)
