Comfortable, no doubt, but it makes Charlie cry! (5)
I believe the answer is:
couch
'comfortable no doubt but it' is the definition.
I can't tell whether this definition defines the answer.
'charlie cry' is the wordplay.
'charlie' becomes 'C' (phonetic alphabet: alpha, bravo, charlie etc.).
'cry' becomes 'ouch' (I've seen this before).
'c'+'ouch'='COUCH'
'makes' acts as a link.
Can you help me to learn more?
(Other definitions for couch that I've seen before include "express" , "Long seat; grass" , "Upholstered seat for more than one" , "Sofa or settee" , "something comfortable to sit on" .)
