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

'drops in cut' is the definition.
'mowed' can be an answer for 'cut' (I've seen this before). I'm not certain of the 'drops in' bit.

'doctor upset water' is the wordplay.
'doctor' becomes 'mo' (medical officer).
'upset' shows that the letters should be reversed in order.
'water' becomes 'dew' (dew is a kind of water).
'dew' written backwards gives 'wed'.
'mo'+'wed'='MOWED'

Can you help me to learn more?

(Another definition for mowed that I've seen is " Cut the grass".)

I've seen this clue in The Guardian.
