Idealistic, somehow given a slant (10)
I believe the answer is:
italicised
'given a slant' is the definition.
The definition suggests a past participle verb which matches the answer.
'idealistic somehow' is the wordplay.
'somehow' indicates an anagram.
'idealistic' anagrammed gives 'ITALICISED'.
Can you help me to learn more?
(Other definitions for italicised that I've seen before include "Drew attention to" , "Inclined to stress" , "Stressed" .)
