Spooner's rude manner, a somewhat dotty way to communicate (5,4)
I believe the answer is:
morse code
'spooner's' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for morse code that I've seen before include "Way of signalling" , "Dots and dashes alphabet" , "Means to communicate" , "Dot and dash signals" , "Dot-dash alphabet" .)
