How you said, "Close that window, I'm freezing"? (6)
I believe the answer is:
coldly
'how' is the definition.
Both the definition and answer are adverbs. Maybe they are linked in a way I don't understand?
'said close that window i'm freezing?' is the wordplay.
I cannot really see how this works, but
'freezing?' could be 'cold' (similar in meaning) and 'cold' is located in the answer.
This explanation may well be incorrect...
'you' acts as a link.
Can you help me to learn more?
(Other definitions for coldly that I've seen before include "without emotion" , "In a chilling manner" , "Unemotionally" .)
