Ram, in the zodiac (5)
I believe the answer is:
aries
I believe this is a double definition.
'ram' is the first definition.
(I have seen 'The Ram ' mean 'aries' so perhaps 'ram' could also mean 'aries')
'in the zodiac' is the second definition.
('Aries' is part of 'zodiac')
(Other definitions for aries that I've seen before include "Stars" , "Zodiacal sign also known as the Ram" , "Sheep" , "Philip -, English poet" , "star group" .)
