When one returned from Yosemite? (4)
I believe the answer is:
time
'when one' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'returned from yosemite?' is the wordplay.
'returned' says the letters should be written in reverse.
'from' indicates a hidden word.
'emit' is hidden within 'yosemite'.
'emit' back-to-front is 'TIME'.
Can you help me to learn more?
(Other definitions for time that I've seen before include "Rhythm" , "The fourth dimension?" , "Spell" , "See 15" , "Speech to close pub" .)
