Contrition about dots and dashes (7)

Ross

I believe the answer is:

remorse

I'm a little stuck... Click here to teach me more about this clue!

'contrition' is the definition.
(I've seen this before)

'about dots and dashes' is the wordplay.
'about' becomes 're' (regarding).
'dots and dashes' becomes 'morse' (I can't justify this - if you can you should believe this answer much more).
're'+'morse'='REMORSE'

Can you help me to learn more?

(Other definitions for remorse that I've seen before include "Contrition for wrongdoing" , "Guilt for a wrong deed" , "Pity" , "Guilty conscience" , "A feeling of deep regret" .)
