Sign meaning 'Arise shakily'? (5)
I believe the answer is:
aries
'sign' is the definition.
(star sign)
''arise shakily'?' is the wordplay.
'shakily'?' indicates an anagram.
'arise' anagrammed gives 'ARIES'.
'meaning' acts as a link.
(Other definitions for aries that I've seen before include "Zodiacal sign also known as the Ram" , "Zodiac ram" , "Sheep" , "Philip -, English poet" , "House" .)
