Fragrant spice clubs think the world of (5)
I believe the answer is:
clove
'fragrant spice' is the definition.
(I've seen this in another clue)
'clubs think the world of' is the wordplay.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'think the world of' becomes 'love'.
'c'+'love'='CLOVE'
(Other definitions for clove that I've seen before include "Spice, used whole or ground" , "Payment for hostage" , "Aromatic bud" , "Flower bud used as a spice" , "Spicy bud - section of garlic" .)
