emends

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

'corrects' is the definition.
(I've seen this before)

'english manuscript including last part' is the wordplay.
'english' becomes 'e' (abbreviation).
'manuscript' becomes 'ms' ('ms' can be a synonym of 'manuscript').
'including' means one lot of letters goes inside another.
'last part' becomes 'end' (end is a kind of part. I am not sure about the 'last' bit.**).
'ms' placed around 'end' is 'mends'.
'e'+'mends'='EMENDS'

Can you help me to learn more?

(Other definitions for emends that I've seen before include "Changes" , "Corrects and improves the text" , "Revises" , "Alters, corrects" , "Makes improvements or corrections" .)
