Gloss over disappearing grove - it's a tax right-off (4)
I believe the answer is:
loss
'a tax right-off' is the definition.
I can't judge whether this defines the answer.
'gloss over disappearing grove' is the wordplay.
'LOSS' is hidden within the letters.
However, I am unsure how the hidden word is indicated.
'it's' is the link.
Can you help me to learn more?
(Other definitions for loss that I've seen before include "(Sports) defeat" , "Deficit" , "Red figures on a balance sheet or ledger" , "Cost" , "(Sporting) defeat" .)
