Little Miss Morse? (3)
I believe the answer is:
dot
This clue could be a double definition.
'little' is the first definition.
(thesaurus)
'miss morse?' is the second definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe there's a link between them I don't understand?
Can you help me to learn more?
(Other definitions for dot that I've seen before include "Little mark" , "Morse symbol; spot" , "One signal used in Morse code" , "Shorter of the two signals used in Morse code" , "Little girl" .)
