"Wordplay in the clues omits one or more letters required for the defined solution." (Only one letter for each of the clues below.) I think that I have the answers for the following two clues, but I can't parse the cryptic bit. Any help would be appreciated. Many thanks.

4D Learner settling further down greatly enjoys books. ?O?E?S

19D Indian meal? Grace is poetic. T?A?I?

4d Novels - 'loves' (with 'l[earner]' further down) + extra 'n'
19d Thalia (Muse of poetry & a Grace) - 'thali' (meal) + extra 'a'

Thanks Lie-in King. I now realise that "Learner settling further down" meant move the L from its original position further along the word! Missed this completely.
