"Frisky nature" describes a spring newborn (7)
I believe the answer is:
taurean
'spring newborn' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'frisky nature describes a' is the wordplay.
'frisky' indicates anagramming the letters.
'describes' means one lot of letters goes inside another (describe can mean to form the outline of).
'nature' anagrammed gives 'tauren'.
'tauren' placed around 'a' is 'TAUREAN'.
Can you help me to learn more?
(Other definitions for taurean that I've seen before include "bovine" , "One born under the sign of the bull" , "One born in April/May" , "person who might be considered bullish?" , "May Day baby, say?" .)
