Resort’s website, editable without a single click, ultimately (7)
I believe the answer is:
waikiki
'resort's website' is the definition.
I can't tell whether this definition defines the answer.
'editable without a single click ultimately' is the wordplay.
'editable' becomes 'wiki' (I can't justify this - if you can you should believe this answer much more).
'without' means one lot of letters goes inside another ('without' can be similar in meaning to 'outside').
'single' becomes 'I' (I as in one).
'ultimately' says to take the final letters.
The final letter of 'click' is 'k'.
'a'+'i'+'k'='aik'
'wiki' placed around 'aik' is 'WAIKIKI'.
Can you help me to learn more?
(Other definitions for waikiki that I've seen before include "Famous Honolulu beach" , "Famous Hawaiian beach" , "Honolulu beach resort" , "Renowned Hawaiian beach" .)
