Late-spring arrival? (6)
I believe the answer is:
gemini
'late-spring arrival?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for gemini that I've seen before include "Zodiac sign - the Twins" , "Sign of the Twins ( 6)" , "Twins star-sign" , "May person" , "Zodiacal twins" .)
