Sound of egg being dropped in caustic solution (8)
I believe the answer is:
acoustic
'sound' is the definition.
Although both the answer and definition are adjectives, I cannot see how one could define the other.
'egg being dropped in caustic solution' is the wordplay.
I cannot quite understand how this works, but
'egg' could be 'o' (an 'o' resembles an egg) and 'o' is present in the answer.
an anagram of 'caustic' is 'acustic' which is present in the left over letters.
This accounts for all the letters.
This explanation may well be incorrect...
'of' is the link.
Can you help me to learn more?
(Other definitions for acoustic that I've seen before include "dispensing with amps?" , "Pertaining to hearing" , "Of the physical properties of sound" , "This guitar is not electric" , "Like sound" .)
