Woman with others on a mountain (7)
I believe the answer is:
everest
'mountain' is the definition.
(Mount Everest)
'woman with others' is the wordplay.
'woman' becomes 'Eve' (Eve is an example).
'with' says to put letters next to each other.
'others' becomes 'rest' (eg the rest of a group).
'eve'+'rest'='EVEREST'
'on a' acts as a link.
(Other definitions for everest that I've seen before include "Himalayan mount" , "The world's highest mountain" , "Where Hillary was" , "High peak" , "Great achievement" .)
