A tune with 'beat' and energy (5)
I believe the answer is:
tango
'a tune' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'beat and energy' is the wordplay.
'beat' becomes 'tan' (tan can mean to beat or hit).
'and' says to put letters next to each other.
'energy' becomes 'go' (go can mean energy or enthusiasm).
'tan'+'go'='TANGO'
'with' is the link.
Can you help me to learn more?
(Other definitions for tango that I've seen before include "Steps" , "Latin American dance takes two to do it" , "Argentine dance" , "Dramatic ballroom dance from Argentina" , "South American dance (for two?)" .)
