Evasive about son being comfortable (4)
I believe the answer is:
cosy
'comfortable' is the definition.
(similar in meaning)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for cosy that I've seen before include "Comfy and snug" , "Warm, secure" , "Intimate" , "Comfortable; teapot cover" , "Warm and comfortable" .)
