Literary type in command amid another sort of A-list (7)
I believe the answer is:
italics
'literary type in command amid another sort of a-list' is the definition.
I can't tell whether this definition defines the answer.
'in command amid another sort of a-list' is the wordplay.
I cannot really see how this works, but
'a' is within the answer.
'in command' could be 'ic' (military abbreviation) and 'ic' is located in the answer.
an anagram of 'list' is 'itls' which is within the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for italics that I've seen before include "List CIA with letters that slant" , "Slanting print" , "Letters in sloping type" , "Typeface with letters slanting to the right" , "Sloping typeface" .)
