Fragrance for one finishing on toilet (8)
I believe the answer is:
lavender
'fragrance' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'one finishing on toilet' is the wordplay.
'one finishing' becomes 'ender' (I can't justify this - if you can you should believe this answer much more).
'on' means one lot of letters go next to another.
'toilet' becomes 'lav' (lavatory).
'ender' after 'lav' is 'LAVENDER'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for lavender that I've seen before include "Shrub with fragrant blue flowers" , "Plant with aromatic mauve flowers" , "shade" , "Pale bluish-purple" , "bloomer" .)
