Comparatively secure from strange fears (5)
I believe the answer is:
safer
'comparatively secure' is the definition.
('safe' can be similar in meaning to 'secure')
'strange fears' is the wordplay.
'strange' indicates an anagram.
'fears' anagrammed gives 'SAFER'.
'from' acts as a link.
(Other definitions for safer that I've seen before include "Less hazardous" , "Less dangerous" , "Less endangered" , "Not so hairy" , "more conservative" .)
