Small piece of land has a tenant (5)
I believe the answer is:
islet
'small' is the definition.
I know that 'small' relates to this answer. I also know that both the answer and definition are singular nouns
'piece of land has a tenant' is the wordplay.
'piece of land' becomes 'isle' (I've seen this before).
'has' is a charade indicator (letters next to each other).
'a tenant' becomes 't' (this might be a standard abbreviation I've not previously seen).
'isle'+'t'='ISLET'
Can you help me to learn more?
(Other definitions for islet that I've seen before include "Cay, for example" , "Tiles to make a small island" , "One of Langerhans's" , "Tiles (anag.)" , "A small piece of territory" .)
