Passionate about braid (5)
I believe the answer is:
rabid
'passionate' is the definition.
(similar in meaning)
'about braid' is the wordplay.
'about' indicates an anagram.
'braid' with letters rearranged gives 'RABID'.
(Other definitions for rabid that I've seen before include "Violent; hydrophobic" , "Fanatical, infected" , "Affected by hydrophobia" , "Infected with hydrophobia" , "Frenzied" .)
