Letters with italic form, perhaps reading through? (8)
I believe the answer is:
learning
'reading through?' is the definition.
'learning' can be an answer for 'reading' ('learn' can be a synonym of 'read'). I am not sure about the 'through?' bit.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for learning that I've seen before include "Aquiring skill or knowledge" , "Lore" , "(Knowledge from) study" , "Discovering, finding out" , "Erudition - education" .)
