Fellow permitted to make flower arrangement (7)
I believe the answer is:
chaplet
'flower arrangement' is the definition.
(chaplet is a kind of flower arrangement)
'fellow permitted' is the wordplay.
'fellow' becomes 'chap' ('chap' can be a synonym of 'fellow'**).
'permitted' becomes 'let' (I've seen this before).
'chap'+'let'='CHAPLET'
'to make' acts as a link.
(Other definitions for chaplet that I've seen before include "flower arrangement" , "Garland or wreath for the head" , "Ornamental wreath worn on the head" , "Little fellow" , "Circular garland for the head" .)
