So-called icecap melting in one spot (9)
I believe the answer is:
localised
'so-called' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives can sometimes define each other.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for localised that I've seen before include "constrained?" , "in a particular place" , "specific area" .)
