Toni pointlessly hires out lavatories (7)
I believe the answer is:
toilets
'lavatories' is the definition.
(I know this)
'toni pointlessly hires out' is the wordplay.
I cannot really understand how this works, but
'hires out' could be 'lets' (I've seen this in another clue) and 'lets' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for toilets that I've seen before include "Lavatories" , "Perfume from iris root" , "Heads" , "Conveniences" , "Plumbing fixtures" .)
