One sat on by Charlie with a cry of pain? (5)
I believe the answer is:
couch
'one sat on' is the definition.
I can't tell whether this definition defines the answer.
'charlie with a cry of pain?' is the wordplay.
'charlie' becomes 'C' (phonetic alphabet).
'with' is a charade indicator (letters next to each other).
'a cry of pain?' becomes 'ouch' (exclamation said when in pain).
'c'+'ouch'='COUCH'
'by' is the link.
Can you help me to learn more?
(Other definitions for couch that I've seen before include "Grass; reclining seat" , "something comfortable to sit on" , "express" , "Sofa or settee" , "Long seat; grass" .)
