Fly back with ordinary character following Sierra (5)
I believe the answer is:
tango
'character following sierra' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'fly back with ordinary' is the wordplay.
'fly' becomes 'gnat' (I've seen this before**).
'back' shows that the letters should be reversed in order.
'with' means one lot of letters go next to another.
'ordinary' becomes 'o' (abbreviation e.g. O-Levels).
'gnat' written backwards gives 'tang'.
'tang'+'o'='TANGO'
Can you help me to learn more?
(Other definitions for tango that I've seen before include "musical piece" , "Argentinian dance form" , "Tonga (anag.)" , "Dance originally from Buenos Aires" , "Steps" .)
