Ice storm raging round island of same size (9)
I believe the answer is:
isometric
'same size' is the definition.
Both the definition and answer are adjectives. Perhaps you can see an association between them that I don't see?
'ice storm raging round island' is the wordplay.
'raging' is an anagram indicator.
'round' indicates putting letters inside.
'island' becomes 'i' (geographical abbreviation).
'ice'+'storm'='icestorm'
'icestorm' with letters rearranged gives 'isometrc'.
'isometrc' placed around 'i' is 'ISOMETRIC'.
'of' is the link.
Can you help me to learn more?
(Other definitions for isometric that I've seen before include "equal in measurement" , "Like some exercises" , "Type of exercise performed against resistant object" , "of equal size" , "Type of angled drawing to scale - eroticism (anag)" .)
