Clearly, in drama, some lines get botched (7)
I believe the answer is:
plainly
'clearly' is the definition.
(synonyms)
'in drama some lines get botched' is the wordplay.
I cannot really understand how this works, but
'in' is within the answer.
'some' could be 'a' and 'a' is located in the answer.
'lines' could be 'll' (an abbreviation for line written twice) and 'll' is present in the leftover letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for plainly that I've seen before include "In unconcealed fashion" , "Clearly" , "obviously" , "Simply" , "... without embellishment" .)
