Deck held in casino, it appearing to the left (5)
I believe the answer is:
patio
'deck' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'held in casino it appearing to the left' is the wordplay.
'held in' indicates the answer is hidden within the clue.
'to the left' is a reversal indicator (reading from right to left).
'oitap' is hidden within 'casino it appearing'.
'oitap' written backwards gives 'PATIO'.
Can you help me to learn more?
(Other definitions for patio that I've seen before include "Paved eating area adjoining house" , "Paved area alongside a house" , "Paved area outside house" , "Where Barbie might be held" , "Inner courtyard" .)
