Sleep over: in the morning getting a cover on top? (6)
I believe the answer is:
panama
'cover on top?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'sleep over in the morning getting a' is the wordplay.
'sleep' becomes 'nap' (a nap is a short sleep).
'over' is a reversal indicator.
'in the morning' becomes 'am' (short for ante meridiem - before noon).
'getting' means one lot of letters go next to another.
'nap' written backwards gives 'pan'.
'pan'+'am'+'a'='PANAMA'
Can you help me to learn more?
(Other definitions for panama that I've seen before include "What may be seen overhead" , "Canal zone" , "'Country, canal and hat (6)'" , "Canal state; hat" , "city" .)
