Italicised type is fanciful (10)

I believe the answer is:

idealistic

I'm a little stuck... Click here to teach me more about this clue!

'fanciful' is the definition.
Both the answer and definition are adjectives. Perhaps there's an association between them I don't understand?

'italicised type' is the wordplay.
'type' indicates an anagram.
'italicised' anagrammed gives 'IDEALISTIC'.

'is' acts as a link.

Can you help me to learn more?

(Other definitions for idealistic that I've seen before include "Striving for perfection" , "Seeking the best" , "Impracticable" , "Naively impractical" , "Utopian" .)

I've seen this clue in the Irish Times and the Irish Times (Crosaire).
