Constrain temperature during bad weather? Assuredly (3,7)
I believe the answer is:
for certain
'assuredly' is the definition.
(I've seen this before)
'constrain temperature during bad weather?' is the wordplay.
'constrain' becomes 'force' (I can't justify this - if you can you should give a lot more credence to this answer).
'temperature' becomes 't' (abbreviation).
'during' indicates putting letters inside.
'bad weather?' becomes 'rain' (rain is an example of bad weather).
't' going into 'rain' is 'rtain'.
'force'+'rtain'='FOR CERTAIN'
Can you help me to learn more?
(Other definitions for for certain that I've seen before include "surely" , "without a doubt" , "definitely" , "Assuredly" .)
