Son caught naked left barely legible note (6)
I believe the answer is:
scrawl
'barely legible note' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'son caught naked left' is the wordplay.
'son' becomes 's' (genealogical abbreviation for son).
'caught' becomes 'c' (cricket abbreviation).
'naked' becomes 'raw' (I've seen this before).
'left' becomes 'l' (common abbreviation).
's'+'c'+'raw'+'l'='SCRAWL'
Can you help me to learn more?
(Other definitions for scrawl that I've seen before include "Long, maybe illegible, piece of writing" , "write hurriedly" , "Write carelessly or badly" , "Hurried writing" , "Quickly pen" .)
