Pulled right out as the night ends (4)
I believe the answer is:
dawn
'as the night ends' is the definition.
I can't tell whether this definition defines the answer.
'pulled right out' is the wordplay.
'right' indicates one should take the final letters (the letter on the right of the word).
'out' becomes 'awn' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
The last letter of 'pulled' is 'd'.
'd'+'awn'='DAWN'
Can you help me to learn more?
(Other definitions for dawn that I've seen before include "Sunrise" , "Threshold" , "Aurora, poetically" , "Break of day" , "Daybreak" .)
