Torment harem, take me away on a donkey! (6)
I believe the answer is:
harass
'torment' is the definition.
(I know that torment is a more specific form of harass)
'harem take me away on a donkey' is the wordplay.
'take' indicates named letters should be taken away.
'away' indicates an anagram (letters move away from their original places).
'on' means one lot of letters goes inside another (as in clothing 'on' a person).
'donkey' becomes 'ss' (I am not sure about this - if you are sure you should believe this answer much more).
'harem' with 'me' taken away is 'har'.
'har' is an anagram of 'hra'.
'hra' placed around 'a' is 'hara'.
'hara'+'ss'='HARASS'
Can you help me to learn more?
(Other definitions for harass that I've seen before include "Pester, badge" , "distress" , "Nag" , "Pester constantly" , "Vex - persecute" .)
