One predicting conditions melting remotest igloo (13)
I believe the answer is:
meteorologist
'one predicting conditions' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'melting remotest igloo' is the wordplay.
'melting' indicates anagramming the letters.
'remotest'+'igloo'='remotestigloo'
'remotestigloo' anagrammed gives 'METEOROLOGIST'.
Can you help me to learn more?
(Other definitions for meteorologist that I've seen before include "Fish, perhaps" , "Weatherperson" , "Weatherman" , "Weather forecaster" , "One studying weather and climate" .)
