Defame most of the islanders (7)

I believe the answer is:

slander

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

'defame most' is the definition.
'slander' can be an answer for 'defame' (synonyms). I'm unsure of the 'most' bit.

'of the islanders' is the wordplay.
'of' indicates the answer is hidden within the clue.
'SLANDER' is hidden in the letters of 'islanders'.

Can you help me to learn more?

(Other definitions for slander that I've seen before include "Malign" , "Injurious defamation by spoken words" , "Speak ill of" , "Defame" , "backbiting" .)

I've seen this clue in The Irish Independent.
