Waltz time? (6)
I believe the answer is:
minute
This could be a double definition.
'waltz' is the first definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'time?' is the second definition.
(time is a kind of minute)
Can you help me to learn more?
(Other definitions for minute that I've seen before include "Extremely small" , "Little - bit of time" , "Measure of time" , "Very short or tiny" , "Small; short time" .)
