Genesis short of celebrity (4)
I believe the answer is:
Here is my best explanation:
'genesis' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'short of celebrity' is the subsidiary indication.
'short' means to remove the first letter.
'of' becomes 'o'.
'celebrity' becomes 'star' (I've seen this in other clues).
'ostar' with its first letter taken off is 'star'.
(Other definitions for star that I've seen before include "- - of Bethlehem", "Glamorous celebrity", "Five-pointed celestial body", "''Twinkle, twinkle, little ...'' (children's song)", "Brilliant person", "Rush", "Luminary", "one of these: ****", "Five-pointed figure" and "Pointed symbol".)
