Highest point for serviette without it disintegrating (7)
I believe the answer is:
everest
'highest point' is the definition.
'Everest' can be an answer for 'point' (Everest is an example). I'm unsure of the 'highest' bit.
'serviette without it disintegrating' is the wordplay.
'without' indicates named letters should be taken away.
'disintegrating' indicates an anagram (I've seen 'disintegrated' mean this).
'serviette' with 'it' taken away is 'servete'.
'servete' with letters rearranged gives 'EVEREST'.
'for' is the link.
Can you help me to learn more?
(Other definitions for everest that I've seen before include "Tallest mountain ..." , "Himalayan mount" , "Great achievement" , "Highest peak" , "Highest Himalayan mountain" .)
